Q

what is circular motion

A

when an object is moving in a circle
* moves out at constant speed
* direction is changing constantly
* velocity is also changing
* accelerating

17
Q

what is centripetal force

A

the full directed towards the center of the circle which allows for acceleration

18
Q

what is Newton’s third Law

A

every action force has an equal and opposite reaction

19
Q

what is inertia mass

A

how difficulty is to change the velocity of an object

20
Q

how is a inertia mass measured

A

force / acceleration
