Chap 11- FORCE concept Test

An example of a balanced force is

• a tug of war game that no one wins.

• a roller coaster going down the first drop.

• a car hitting a wall.

• a person pushing a shopping cart.

Julio and Luis need to move a box that contains a 35 N TV. Julio pushes with 250 N, and Luis pushes with 100 N. If both boys are pushing in the same direction (and assuming no friction), what is the net force?

• 250 N

• 350 N

• 135 N

• 150 N

The force that causes 2 objects with mass to be pulled towards each is called...

• acceleration

• friction

• gravity

• inertia

A magnet is places near a pile of steel paper clips. Which will most likely occur?

• The magnet will provide a balanced force, causing the paper clips to spin in circles.

• The magnet will provide an unbalanced force, keeping the paper clips stationary.

• The magnet will provide a balanced force, pushing paper clips away from it.

• The magnet will provide an unbalanced force, pulling the paper clips towards it.

What is force?

• A force is a push or a pull upon an object resulting from the object's interaction with another object.
• something used in Star Wars 
• It is the amount of space between two points.
• It is Superman's power

A ball is rolling down a ramp. What unbalanced force is affecting the ball and its motion the most?

• Friction with the ramp is causing the ball to slow down.

• Friction with the air is causing the ball to speed up.

• Gravity is causing the ball to speed up.

• The person pushing the ball is causing it to speed up.
