Force - balanced and unbalanced

Forces are measured in

• Newtons

• grams

• metres

• millilitres

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

What is the definition of a force?

• Net force equal 0N and there is no change in the object's motion

• the overall force acting on an object after all forces are combined

• a push or a pull that acts on an object

• The force does not equal 0N, the object accelerates

What is the definition of net force?

• a push or a pull that acts on an object

• Net force equal 0N and there is no change in the object's motion

• the overall force acting on an object after all the forces are combined

• The force does not equal 0N, the object accelerates
