Electric energy

Dribbling a basketball

Stretching a rubberband

Compressing or Stretching a spring

All of the above

The first car and second car continue to roll down the track together.

The first car stops completely and transfers its kinetic energy to the second car.

The first car bounces off of the second car and the second car starts moving slowly down the track

The first car transfers its potential energy to the second car to satisfy the law of conservaation

Electricity is converted to kinetic energy

Electricity is converted to mechanical and thermal energy

Electricity is used efficiently to dry hair

The electricity is tranformed into elastic and chemical energy

Ozone gas which protects the Earth from pollution and global warming.

warmed areas which then create currents making the wind blow transforming the sun's light into kinetic energy

the layers of the atmosphere so that weather can happen and rain can fall

water currents that result in hydropower and photosynthesis.

Gravitational Potential Energy

Elastic Energy

Chemical Energy

Kinetic Energy

Both depend on the object's mass

Gravitational Potential Energy depends on the height the object is lifted up to

Kinetic Energy depends on speed of the object's motion

All of the above

be created if we are careful and work very hard

be created with the right conditions and tools

not be created or destroyed it can only be changed

be created and destroyed and changed into different forms
