Force and Motion

Force and Motion

Multiple Choice

Savannah concludes that in each experiment, the marble hit the cup with a different amount of force.

Which best supports her conclusion?

• the height of the ramp in each experiment

• the time the marble took to reach the cup in each experiment

• the mass of the marble used in the experiments

• the distance that the cup moved in each experiment

Multiple Choice

Which statement best explains why the marble had a different amount of energy in each experiment?

• The marble started with different speeds.

• The times it took for the marble to hit the cup were different.

• The marble had a different speed each time it hit the cup.

• The cup moved a different distance each time the marble hit it.

Multiple Choice

Which question was Savannah most likely trying to answer by completing this experiment?

• How does the height of the ramp affect the mass of the marble?

• How does the height of the ramp affect the speed of the marble?

• How does the height of the ramp affect the time the marble rolls before stopping?

• How does the height of the ramp affect the distance the marble rolls before stopping?

Multiple Choice

Which statement correctly predicts the answer to Savannah's question in Part A?

• When the height of the ramp is decreased, the time the marble will roll before stopping increases

• When the height of the ramp is increased, the marble will not roll as far before stopping.

• When the height of the ramp is increased, the speed of the marble will increase.

• When the height of the ramp is decreased, the mass of the marble will decrease.

Multiple Choice

Why does the recording look different at time A and time C?

• The temperature of the ground at time A was different from the temperature at time C.

• The angle of the ground at time A was different from the angle at time C.

• The amount the ground moved at time A was different from the amount the ground moved at time C.

• The strength of the wind close to the ground at time A was different from the strength of the wind close to the ground at time C.

Multiple Choice

Which evidence did Aiden most likely use to reach his conclusion?

• Point 1 is farthest from the sensor.

• Point 1 is closest to the top of the ramp.

• The car took the most time to reach the end of the ramp from point 1.

• The car had the greatest speed at the sensor when it was released from point 1.
