8.1 Collisions Review

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, slowing it down.

Front

True or False? Air Resistance is a force that can slow down the speed of an object.

Back

True

Front

What happens to surface temperature when friction between surfaces increases?

Back

The surface temperature increases as the friction between surfaces increases.

Front

True or False? The surface temperature will decrease as the friction between surfaces increases.

Back

False

Front

If the head wind increases, what happens to the friction needed between tires and the road?

Back

There will need to be more friction between tires and the road to keep the same amount of kinetic energy transfer.

Front

Energy is transferred through what in collisions?

Back

Energy is transferred through contact forces in collisions.

Front

What is transferred in a collision?

Back

Energy is transferred in a collision.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the relationship between friction and motion?

Back

Friction is a force that opposes motion, affecting the speed and direction of moving objects.

Front

What is the effect of increased friction on an object's speed?

Back

Increased friction generally slows down an object's speed.
