Martin needs to push a box up a ramp. Which forces will Martin work against MOST when he pushes the box up the ramp?

• friction and gravity

• inertia and magnetism

• magnetism and friction

• gravity and momentum

Students set up the investigation shown.

What can the students do to increase the speed that the marble will roll down the ramp?

• add a layer of carpet to board

• lower the height of the board

• use a longer board for the ramp

• replace the board with a smoother board

Two balls rolled down two identical inclined planes. The balls were exactly the same mass and size, but one ball rolled down the inclined plane faster. Identify a possible reason that one ball rolled faster than the other ball.

• One ball was red and the other ball was blue.

• One ball was new and the other ball was old

• One ball was shiny and the other ball was dull.

• One ball was sticky and the other ball was smooth.

The following trucks are pushed with the same amount of force.

Which truck will roll the farthest?

• Truck 1

• Truck 2

• Truck 3

• Truck 4

Wind is acting on the sails of a boat as shown in the illustration below. The force of the wind is greater than the force of the water.

Which will most likely happen to the boat if the wind increases?

• The boat will speed up.

• The boat will slow down.

• The boat will stop moving.

• The boat will keep moving at the same speed.

Which determines whether an object hit by an unbalanced force will change direction or continue moving in the same direction?

• the direction in which the object was already moving

• the direction in which the unbalanced force is traveling

• the amount of gravity present when the unbalanced force hit the object

• the amount of friction present when the unbalanced force hit the object

A force causes an object to be in motion. Which will most likely happen to the motion of the object if a weaker force begins acting on the object in the opposite direction?

• The speed of the object will increase.

• The speed of the object will decrease.

• The speed of the object will remain the same.

• The object will immediately stop moving.
