Force and Motion

What question were they most likely trying to answer?

• Does the mass of a car affect the change in motion?

• Does the force on a car affect the change in motion?

• Does the distance the car travels affect the time?

• Does the mass of a car affect the distance the car travels?

What would most likely happen to the motion of the box if you poured oil on the ramp?

• It will slow the box because the force of friction will be increased.

• It will speed up the box because the force of friction will be increased.

• It will slow the box because the force of friction will be reduced.

• It will speed up the box because the force of friction will be reduced.

How should he make the graph of his data?

• He should make a line graph with mass on the “X” axis and distance on the “Y” axis.

• He should make a line graph with mass on the “y” axis and distance on the “X” axis.

• He should make a bar graph with mass on the “X” axis and distance on the “Y” axis.

• He should make a bar graph with mass on the “y” axis and distance on the “X” axis.

Which hypothesis will most likely be supported by the results of the investigation?

• When a balanced force is applied the block with the greatest mass will move fastest.

• When an unbalanced force is applied the block with the least mass will move fastest.

• When a balanced force is applied the speed of the object will not change.

• When an unbalanced force is applied the speed of the object will not change.
