newton's three laws of motion

Question 1

what are newton’s three laws of motion?

Answer 1

inertia, acceleration, action-reaction

Question 2

what is inertia?

Answer 2

a body in motion tends to stay in motion and a body at rest tends to stay at rest unless acted upon by an external force

Question 3

what is acceleration?

Answer 3

force = mass x acceleration
the more force applied, the more acceleration and the more mass, the more force required

Question 4

what is action-reaction?

Answer 4

for every action, there is an equal and opposite reaction

Question 5

what is an example of inertia?

Answer 5

a gymnast in a stationary position on a beam will remain in that state until acted upon by an external force

Question 6

what is an example of acceleration?

Answer 6

a football lineman pushing a blocking sled
as more mass is added, the lineman must use more force and the more force they apply, the more acceleration the sled will have

Question 7

what is an example of action-reaction?

Answer 7

a basketball player jumping applies a force onto the ground
in turn, the ground applies an equal and opposite force propelling the player upwards
