Q

What is Newton;s first law of motion?

A

Law of inertia

A body at rest will stay at rest, and a body in motion will stay in motion unless acted upon by an external force

Q

What is Newton’s second law of motion?

A

Law of acceleration
Force acting on a body in a given direction is equal to the mass times the acceleraton in that direction.
Force= Mass x Accel

Q

What is a translatory motion?

A

when an object in motion in not tied down, all parts move in same direction and at same speed.

Q

What are the first two types of levers?

A

Located outside of the body, wheelbarrow and crow bar. the motive force is farther away from axis making the force less to move it.

Q

what is the third type of lever?

A

What happens internally of the body, the force acts between the axis and resistance force, Farther away you are moving something with your body the harder. Ex. why weightlifters have shorter arms and legs.
