Circular Motion

Question 1

Centripetal force

Answer 1

Net force keeping an object moving in a circular path

Centri = center
Petal = seeking

Question 2

Newton’s first law

Answer 2

An object in motion will stay in motion in a straight line, until acted upon an outside force

Question 3

Newton’s second law

Answer 3

A net force/mass gives acceleration

Question 4

Newton’s third law

Answer 4

For every action there is an equal and opposite reaction

Question 5

Circular motion is…

Answer 5

Newton’s first law: an object in motion will stay in motion in a straight line, until acted upon an outside force

Question 6

Uniform circular motion

Answer 6

Motion in a circular path at a constant speed (acceleration = change in velocity)

NOT velocity

Question 7

Centripetal acceleration

Answer 7

Change in velocity towards the center

Question 8

Centrifugal

Answer 8

Newton’s third law: for every action there is an equal and opposite reaction

Question 9

Tangent

Answer 9

A line that touches a circle
