3.1 force and motion

What is kinetic energy?

• The energy of movement
• stored energy

What is potential energy?

• energy of movement
• stored energy

Which has higher potential energy?

• A boy on a bicycle sitting at the top of a hill
• a boy on a bicycle flying down a hill

What is motion?

• The change in position, direction and speed of an object
• The speed and acceleration of an object

What is speed

• The direction something is headed
• how fast or slow something is going

What is position?

• the location of something
• how fast or slow something is going

What are words that would describe direction?

• Fast, slow, stopped
• up, down, forward, backward

What is a force?

• any push or pull that makes an object move, stop or change speed
• a type of acceleration that makes things move

Things require a force in order to move or change positions

• true
• False

Things cannot move or stop without another force acting upon it (things in motion stay in motion, things at rest, stay at rest unless a force acts upon it.)

• true
• False
