1 of 81 of 8 Items Question A student collects data during an investigation about inertia and acceleration. If the force acting on the objects is constant, which statement about inertia and acceleration is supported by the data? (1 point) Responses An object with less mass has less inertia which causes it to speed up less quickly. An object with less mass has less inertia which causes it to speed up less quickly. An object with a higher mass has less inertia which causes it to speed up more quickly. An object with a higher mass has less inertia which causes it to speed up more quickly. An object with a higher mass has more inertia which causes it to speed up less quickly. An object with a higher mass has more inertia which causes it to speed up less quickly. An object with less mass has more inertia which causes it to speed up more quickly. An object with less mass has more inertia which causes it to speed up more quickly.

2 of 82 of 8 Items Question The picture shows a physics lab set up. Why does the disc fall straight down into the glass when we quickly pull the index card away from the glass in a horizontal direction? (1 point) Responses static friction static friction kinetic friction kinetic friction inertia inertia equilibrium equilibrium Skip to navigation page 13 of 13
The disc falls straight down into the glass when we quickly pull the index card away from the glass in a horizontal direction due to inertia.
3 of 83 of 8 Items Question A student is riding the school bus. The bus stops as the driver applies the brakes. Which of these statements best describes this situation?(1 point) Responses The school bus does not lose or gain kinetic energy. The school bus does not lose or gain kinetic energy. The bus is gaining energy because of friction. The bus is gaining energy because of friction. There is no force acting on the bus so it stops moving. There is no force acting on the bus so it stops moving. A force is changing the motion of the bus. A force is changing the motion of the bus. Skip to navigation page 13 of 13
A force is changing the motion of the bus.

Which two forces are acting on the baseball?(1 point) Responses electricity and friction electricity and friction gravity and friction gravity and friction inertia and magnetism inertia and magnetism nuclear and inertia
gravity and friction.
Two people are in a rowboat on a river. The current of the river water carries them at a speed of five meters per second even when they are not rowing. What will happen to the boat's motion of no other forces act on the boat?(1 point) Responses The boat's speed will increase. The boat's speed will increase. The boat's speed will decrease. The boat's speed will decrease. The boat's speed will stay the same. The boat's speed will stay the same. The boat will change direction.
The boat's speed will stay the same.
