• It will stay still

• It will move

• It will disappear

• It will become heavier

A car speeding up is an example of a change in:

• Direction

• Rubbing your hands together

• A bird flying

• A magnet attracting a paperclip

What happens when two equal forces act on an object in opposite directions?

• The object speeds up

• The object slows down

• The object changes direction

• The object stays still
