Physical Science Final Review

Front

What happens to particles in a solid when the temperature increases?

Back

Particles speed up.

Front

In which position is the kinetic energy at a maximum?

Back

Point C.

Front

During which interval is the object not moving?

Back

Only at point A.

Front

In which position is the kinetic energy increasing?

Back

Point B.

Front

Calculate the kinetic energy of a truck that has a mass of 2900 kg and is moving at 55 m/s.

Back

4,386,250 J.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to the kinetic energy if the velocity of an object doubles?

Back

The kinetic energy increases by a factor of four.

Front

What is the relationship between temperature and particle motion in solids?

Back

As temperature increases, particle motion increases.

Front

Define potential energy.

Back

The energy stored in an object due to its position or state.
