Understanding Checkpoint: Force

Force is measured in

• Watts.

• Joules.

• Newtons.

• horse power.

Arrows are used to represent force, they represent both

• strength and direction.

• direction and speed.

• strength and speed.

• mass and strength.

The formula to calculate force is:

• mass X weight.

• mass X acceleration.

• mass / speed.

• weight X acceleration.

The force that always acts in a direction opposite to the motion of an object is:

• an applied force.

• friction.

• gravity.

• magnetic.

Jeff pushes a box across the floor. What causes the box to move?

• an applied force

• gravity

• electric

• inertia

True or False: Because force is a vector measurement, it has both magnitude and direction.

• True

• False

True or False: Gravity is the force that pulls objects toward Earth.

• True

• False

True or False: Friction can be represented with a vector.

• True

• False

Friction is a force that acts in the (a)   direction of the way the object is trying to move.

• parallel

• opposite

• same

• perpendicular

A bowling ball going down a bowling lane has (a)   friction.

• rolling

• static

• sliding

• fluid
