laws of motion

Question 1

what is Newtons first law of motion?

Answer 1

A body in motion stays in motion at constant velocity
and a body at rest stays at rest unless acted upon by a
net external (unbalanced) force.

Question 2

what is Newtons first law also known as?

Answer 2

Inertia

Question 3

what are the implications of Newtons first law?

Answer 3

If there is zero net force on a body, it cannot
accelerate, and therefore must move at constant
velocity. it cannot turn, speed up or slow down.

Question 4

the higher the the mass, the ____ the inertia

Answer 4

greater

Question 5

what is zero net force?

Answer 5

when forces on an object are balanced, there is no net force

Question 6

what is the normal force?

Answer 6

the push that a surface (or object) exerts back on an object that comes into contact with it

Question 7

what does the normal force always do?

Answer 7

act perpendicular to, and away from, the surface.

Question 8

what is Newtons second law?

Answer 8

A body accelerates when acted upon by a net external force. The acceleration is proportional to the net force and is in
the direction which the net force acts.

Question 9

what is the equation for weight?

Answer 9

w=mg

Question 10

what is Newtons third law?

Answer 10

For every action there exists an equal and opposite reaction.
