Energy Review

Front

What happens to the kinetic energy of an object if its velocity is doubled?

Back

The kinetic energy quadruples.

Front

What regions on a velocity-time graph indicate an increase in velocity?

Back

Regions 1, 4, 8, and 10.

Front

What happens to the kinetic energy of a block sliding with friction as it slows down?

Back

The block's kinetic energy decreases, and thermal energy increases on both the block and surface.

Front

What type of energy is stored in a stretched rubber band?

Back

Elastic potential energy.

Front

What is the term for a change in the type of energy?

Back

Energy conversion.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

What is the formula for kinetic energy?

Back

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

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is elastic potential energy?

Back

The energy stored in an object when it is stretched or compressed.
