Force 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

A bus starts from rest and accelerates to 14 m/s in 4 s. What is the average acceleration of the bus?

• 3.5 m/s2

• 5.9 m/s2

• 10.5 m/s2

• 24 m/s2

The picture of the position vs. time graph shows an object that is...

• not moving 
• accelerating/slowing down. 

What kind of acceleration is shown here?

• positive
• negative
• none
• varies

What is the acceleration of this object?

• -3 m/s

• +3 m/s

Name the missing force...

• weight force
• normal force
• applied force
• frictional force

• 
• 
• 
• 

Which way is the object moving?

• it's either not moving or moving at a constant speed due to balanced forces

• to the right

• to the bottom

• up
