Forces and Motion Review

Which type of force(s) will cause a change in an object's motion?

• gravity
• zero net force
• balanced forces
• unbalanced forces

friction is a force that acts 

• in the same direction as the motion
• opposite to the direction of the motion
• opposite to the applied forces
• the same direction as the applied force

What Unit do we Measure Force in?

In a tug of war the left team pulls with a force of 200N. The right team pulls with a force of 150N.What is the net force?

• 50N to the left.
• 350N to the left.
• 350N to the right.
• 50N to the right.

A balanced force has 

• no net force
• some net force
• a wee bit of net force
• a lot of net force

Balanced or Unbalanced?

• Balanced 
• Unbalanced

What happens when two forces act in the same direction?

• They cancel each other out.
• The stronger one prevails.
• Their strengths are added.
• Their sum divided by the two is the total force.
