Choose the true statements from the choices below

• The distance between dots on a motion diagram represents the object's change in position during that time interval

• A large space between dots indicates that the object was moving fast

• A small space between dots indicates that the object was moving slowly

• Both images in question show an object moving at constant velocity

If the object was moving from left to right, what type of motion created the dot diagram for Z?

• an object at rest

• an object moving with a constant velocity

• an object getting faster

• an object getting slower

What type of motion created the dot diagram for X?

• an object at rest

• an object moving with a constant velocity

• an object getting faster

• an object getting slower

In which crash did the puck experience a stronger force?

• The puck didn't experience a force. Only the paddles experienced force.

• Crash 1: The force of the red paddle was stronger in this crash because it has less mass, so the force on the puck was stronger.

• Crash 2: The force of the purple paddle was stronger in this crash because it has more mass, so the force on the puck was stronger.

• The puck experienced the same force in both crashes.

In which crash did the skateboard experience the stronger force? Why?

• Crash 1: the force on the empty cart was stronger in this crash.

• Crash 2: the force on the full cart was stronger in this crash.

• The diagram doesn't tell you anything about the force on the skateboard.

• The skateboard experienced THE SAME force in both crashes.

In which crash does the satellite experience a stronger force?

• It was the same force in both crashes.

• Crash 1: The force exerted by the black asteroid would have been stronger in this crash, so the force on the satellite would also have been stronger.

• The diagram doesn't tell you anything about the force on the satellite.

• Crash 2: The force exerted by the gray asteroid would have been stronger in this crash, so the force on the satellite would also have been stronger.
