Forces can be described as
pushes
pulls
pushes or pulls
I don't know
What happens if forces are balanced?
The object will move left
The object will move right
The object will keep moving at the same speed in the same direction
The object will keep moving in the same direction but slow down
What happens if forces are unbalanced?
The object will changed direction, shape or speed
It will move left
It will move right
It will only slow down
Forces are represented using which shape?
squares
triangles
circles
arrows
When do we see friction?

What can we say about the forces of an object that is not moving?
there must only be one force acting on it
The forces must be balanced
the forces must be unbalanced
it must be very heavy
