1

What is Newton’s first law?

A moving object will stay at the same velocity unless an external force acts upon it or a stationary object will remain at rest unless an external force acts upon it

2

What is important when looking at how the velocity of an object changes?

The overall resultant force

3

What will happen to the velocity of an object when balanced forces act upon it?

It will not change

4

What will unbalanced forces cause the velocity to do?

Change

5

An objects velocity is constantly changing but the speed is constant, why?

They are travelling in a circle

6

What is the centripetal force?

Resultant force that causes a change in direction

7

Where does the centripetal force act towards?

The center of the circle

8

What are types of force that make objects move in circular paths?

Tension e.g. in wires, gravity and friction
