Front

What type of energy is stored in gasoline and rocket fuel?

Back

Chemical Energy

Front

What happens to the kinetic energy of an object as it speeds up?

Back

The kinetic energy increases.

Front

Is the statement 'Energy stored in a compressed spring is elastic potential energy' true or false?

Back

True

Front

Calculate the kinetic energy (KE) of a jogger with a mass of 60 kg moving at a speed of 3 m/sec.

Back

270 J

Front

Does lowering an object increase its gravitational potential energy?

Back

False

Front

What is the formula for calculating kinetic energy?

Back

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

Front

Define gravitational potential energy.

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object.

Front

What type of energy is associated with the position of an object in a gravitational field?

Back

Gravitational Potential Energy

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.
