Question 8

What is Newton’s first law of motion?

Answer 8

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force

Question 9

Define Mass?

Answer 9

The amount of matter in an object, independent of its size or any forces acting on the object. Both a property of a physical object and how resistant an object is to acceleration.

Question 10

What is Newton’s second law of motion?

Answer 10

the acceleration and net external force are directly proportional, and there is an inversely proportional relationship between acceleration and mass.

Question 11

What is Newton’s third law of motion?

Answer 11

whenever one body exerts a force on a second body, the second body exerts a force that is equal in magnitude and opposite in direction on the first body.
