Netwon's Laws of Motion

Question 1

What is Newton’s first law of motion?

Answer 1

Newton’s first law of motion is the law of inertia. This means that an object at rest stays at rest, while an object in motion stays in motion. This is true unless acted upon by an unbalanced force.

Question 2

What is Newton’s second law of motion?

Answer 2

Newton’s second law of motion is the law of F= m a. This law states that the acceleration of an object depends on its mass and the force applied.

Question 3

What is Newton’s third law of motion?

Answer 3

Newton’s third law of motion is the law of action and reaction. This law states that every action has an equal and opposite reaction.

Question 4

True or False: Aerodynamics is the study of the air.

Answer 4

This is true Aerodynamics is the study of air and everything is affected by it even a car.

Question 5

Which law does this example relate to?: A rocket launching.

Answer 5

This example relates to the third law. It is an equal and opposite reaction.

Question 6

What is force?

Answer 6

Force is the push or pull of an object using its mass to change its velocity.

Question 7

True or False: Friction lets an object go on forever.

Answer 7

False. If an object has friction, the object will eventually stop because of the force of friction between the ground and the object.

Question 8

What are 3 forces used in everyday objects?

Answer 8

Friction, gravity, and applied force.
