- 4. Multiple Choice
Two books are laying on a tabletop. Without picking them up how could you determine which has the greatest inertia.
Give each one a push, the one that moves the easiest has less mass thus less inertia
Look at them, the larger one will have more inertia
Neither one has inertia they are not moving
It is impossible to tell

- 8. Multiple Choice
Beth exerts 14N of force to propel a 4.5 kg bowling ball down the lane. Describe how the ball will travel.
The bowling ball accelerates toward the pins at 3.1 m/s2.
The inertia increases to 6.75 m/s2 as the ball approaches the pins.
It descends on the pins at the end of the lane with a velocity of 17 m/s2.
The ball shows the result of unbalanced forces with a momentum of 9.6 m/s2.
- 9. Multiple Choice
A person is on a raft. The person exerts a force on the raft, causing the raft to move. The person also moves in the opposite direction.
Which statement BEST explains why the person and the raft moved in opposite directions?
Second law of motion
Action and reaction forces
Person wanted the raft to move
Force is the product of mass and acceleration
- 10. Multiple Choice
Two trucks, as seen above, were driving down a two lane road and were involved in a head-on crash. How does the force experienced by the driver of each truck compare?
The forces on the two drivers are equal
The force on the faster truck is greater
We cannot calculate the force on the drivers.
The force on the driver of the larger truck is less than the driver of the smaller truck.
