7. Is this true or false? [For the same mass, more acceleration requires more force]

True

False

The statement is true because according to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Therefore, to achieve a greater acceleration for an object with the same mass, a greater force is required.

Explanation

The statement is true because according to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Therefore, to achieve a greater acceleration for an object with the same mass, a greater force is required.

8. What is the formula that was stated in Newton's 2nd Law of Motion?

The formula stated in Newton's 2nd Law of Motion is F=ma. This equation represents the relationship between force (F), mass (m), and acceleration (a). It states that the force acting on an object is directly proportional to the mass of the object and the acceleration it experiences. The equation F=MA is incorrect because the acceleration is represented by a lowercase "a" and not an uppercase "A".

9. Fill in the blank below. _____________ is the force pulling all object toward each other.

Gravity is the force pulling all objects toward each other. It is a fundamental force of nature that causes objects with mass to attract each other. The strength of gravity depends on the mass of the objects and the distance between them. It is responsible for keeping planets in orbit around the sun, and objects on Earth grounded. Gravity is a universal force that affects everything in the universe.

Laws Of Motion and Calculus

Isaac Newton is famous for his work on the laws of motion and calculus. He formulated the three laws of motion, which describe the relationship between an object's motion and the forces acting upon it. These laws are fundamental principles in the field of physics. Additionally, Newton made significant contributions to the development of calculus, a branch of mathematics that deals with rates of change and the calculation of derivatives and integrals. Newton's work in both areas revolutionized the fields of physics and mathematics and laid the foundation for many scientific advancements.

12. Fill in the blank below. Inertia is the property of an object that _______ change of motion. (Answer is all lowercase)

Inertia is the property of an object that resists change of motion. It refers to the tendency of an object to maintain its current state of motion, whether it is at rest or moving at a constant velocity. This resistance to change in motion is due to the object's mass and is described by Newton's first law of motion.

13. Fill in the blank below. Newton's 1st Law - An object at rest will stay at rest unless acted on by an unbalnce force. An object in motion will stay in motion unless acted upon by ______ ___________ _____________. (Answer is all lowercase)

An object in motion will stay in motion unless acted upon by an unbalanced force. This means that if there is no unbalanced force acting on the object, it will continue to move with the same velocity. The presence of an unbalanced force can change the object's velocity, either by speeding it up, slowing it down, or changing its direction. Therefore, the correct answer is "an unbalanced force".

14. Fill in the blank below. Newton's 2nd Law - The acceleration of an object is ____________ to the force acting on it and inversely ___________ to its mass. (The answer you put in, will fill in for both blanks) (Answer is all lowercase!)

According to Newton's 2nd Law, the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass. This means that as the force acting on an object increases, its acceleration also increases. Similarly, as the mass of an object increases, its acceleration decreases. Therefore, the correct answer for the blank is "proportional".

15. Fill in the blank below. Newton's 3rd Law - Whenever one object exerts a force on another object, the second exert an _____ _______ ______ on the first. (Answer is all lowercase)

Newton's 3rd Law states that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first. This means that the force exerted by the second object is of the same magnitude as the force exerted by the first object, but in the opposite direction. This law helps to explain the concept of action and reaction, where every action force has a corresponding reaction force.
