Motion Review

What kind of forces must be present for motion to occur?

• balanced

• unbalanced

• opposing

• Newtons

If the forces acting on an object are unbalanced, what will happen to the object's velocity?

• The velocity will change.

• The velocity will remain constant.

• The velocity becomes speed only .

• The velocity becomes direction only.

Which of the forces acting on this object has the greatest magnitude?

• 6 N

• 3 N

• 20 N

• +y, _+x

Which direction will this object move?

• Up

• Down

• Left

• Right

How would you describe the forces acting on this object?

• Balanced

• Unbalanced

Which direction will this object move?

• Up

• Down

• Left

• Right

• None

A force of 25 N is pushing down on an object, while a force of 50 N is pushing up on the object.

What is the net force acting on the object and which direction will it move?

• 75 N, up

• 75 N, down

• 25 N, up

• 25 N, down
