Which law states that an object in motion stays in motion unless acted upon by an external force?
- A.
Law of Inertia
- B.
Newton's Second Law
- C.
Law of Universal Gravitation
- D.
Law of Conservation of Energy
Correct Answer
A. Law of InertiaExplanation
Newton's First Law of Motion, also known as the Law of Inertia, explains that objects remain in their state of motion unless an external force interferes. This means that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an unbalanced force. In simpler terms, objects tend to resist changes in their motion. This law is fundamental in understanding the behavior of objects in the absence of external forces. It helps explain why objects behave the way they do and is a key concept in physics.Rate this question:

What is the frequency of a wave if its period is 0.2 seconds?
- A.
5 Hz
- B.
2 Hz
- C.
0.2 Hz
- D.
10 Hz
Correct Answer
A. 5 HzExplanation
Frequency is the reciprocal of the period. Frequency = 1 / period. Therefore, 1 / 0.2 = 5 Hz. This means that the wave completes 5 cycles in one second. The higher the frequency, the shorter the period of the wave. This relationship is important in understanding the behavior of waves in various applications, such as sound and light. Higher frequency waves have more energy and can carry more information. For example, radio waves with higher frequencies can transmit more data compared to lower frequency waves. Understanding the relationship between frequency and period is crucial in optimizing communication systems for efficient data transmission.Rate this question:

What is the definition of displacement?
- A.
An object that is lost without any scientifically explained reason
- B.
A vector that points from an object's initial position to its final position and has a magnitude that equals the shortest distance between two points
- C.
A vector that points from an object's initial position to its final position and has a magnitude that equals the greatest distance between two points
- D.
None of the above
Correct Answer
B. A vector that points from an object's initial position to its final position and has a magnitude that equals the shortest distance between two pointsExplanation
In the context of physics, displacement is defined as a change in the position of an object. It is a vector quantity, which means it has both magnitude and direction. The magnitude of the displacement vector is the shortest distance between the initial and final positions of the object, and the direction is from the initial position to the final position. Displacement is different from distance traveled, as it only considers the straight line between the starting point and the ending point, not the actual path taken. For example, if you walk in a circle and end up back where you started, your displacement would be zero, even though you traveled a certain distance.Rate this question:

The flow of electric current is opposite to the flow of electrons in a medium
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In a medium, electric current is the flow of charged particles, which are usually electrons. However, the direction of current is defined as the direction in which positive charges would flow. Since electrons have a negative charge, their actual flow is opposite to the direction of current. Therefore, the statement that the flow of electric current is opposite to the flow of electrons in a medium is true.Rate this question:

What is the definition of average velocity?
- A.
Average Velocity = displacement/elapsed time.
- B.
Elapsed time = Distance/speed.
- C.
Velocity = Elapsed time/acceleration.
- D.
None of the above.
Correct Answer
A. Average Velocity = displacement/elapsed time.Explanation
Average velocity is defined as the displacement of an object divided by the elapsed time. Displacement refers to the change in position of an object, while elapsed time is the total time taken for that change to occur. By dividing the displacement by the elapsed time, we can determine the average rate at which an object is changing its position over a given time period. Therefore, the correct answer is "Average Velocity = displacement / elapsed time".Rate this question:

What is the hindrance to the flow of electrical current known as?
- A.
Resistance
- B.
Potential difference
- C.
Inductance
- D.
Conductance
Correct Answer
A. ResistanceExplanation
Resistance is the hindrance to the flow of electrical current. It is a property of materials that opposes the flow of electric current through them. When a voltage is applied across a conductor, the resistance causes the flow of current to be reduced. Resistance is measured in 'ohms' and is influenced by factors such as the material's composition, length, cross-sectional area, and temperature.Rate this question:

What is the resistance of a conductor directly proportional to?
- A.
Cross section
- B.
Length
- C.
Density
- D.
Melting point
Correct Answer
B. LengthExplanation
The resistance of a conductor is directly proportional to its length. This means that as the length of the conductor increases, the resistance also increases. This relationship can be explained by the fact that as the length of the conductor increases, the number of collisions between electrons and atoms within the conductor also increases. These collisions impede the flow of electrons, resulting in a higher resistance. Therefore, the longer the conductor, the higher its resistance will be.Rate this question:

______________ does not reveal about the direction of the motion. To describe how fast an object moves and the direction of its motion, we need the vector concept of _____________.
- A.
Speed - Velocity
- B.
Distance - Time
- C.
Acceleration - Velocity
- D.
Mass - Force
Correct Answer
A. Speed - VelocityExplanation
Speed is a scalar quantity that only describes how fast an object is moving, without regard to its direction. Velocity, on the other hand, is a vector quantity that includes both the speed and direction of motion. To fully describe the motion of an object, we need to know both how fast it is moving and in what direction it is moving.Rate this question:

____________is the value of acceleration due to gravity on Earth.
Correct Answer
9.8 m/s²Explanation
The standard acceleration due to gravity on Earth is approximately 9.8 m/s² This means that any object near the surface of the Earth will experience a downward acceleration of 9.8 m/s² due to gravity. This value can vary slightly depending on location and altitude on Earth. For example, at higher altitudes, the acceleration due to gravity may be slightly less than 9.8 m/s². Additionally, factors such as the Earth's rotation and local geology can also affect this value.Rate this question:
- 15.
_________is the formula for kinetic energy.
Correct Answer
KE = ½ mv²Explanation
Kinetic energy is given by the formula KE = ½ mv², where m is mass and v is velocity. This formula demonstrates that kinetic energy is directly proportional to both mass and velocity. Therefore, an object with a greater mass or velocity will have a higher kinetic energy. Additionally, kinetic energy is a scalar quantity, meaning it only has magnitude and no direction. This formula is crucial in understanding the relationship between an object's mass, velocity, and kinetic energy.Rate this question:
