Unit 8.1 Flashcard 7

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What causes an object to stop moving?

Back

Friction is the primary force that causes an object to stop moving.

Front

How can friction be increased?

Back

Friction can be increased by using rougher surfaces or adding materials like sand.

Front

Which surface has the highest friction?

Back

Rough surfaces, such as concrete or carpet, have higher friction compared to smooth surfaces like ice.

Front

What type of energy is transferred when a cart moves a box?

Back

Kinetic energy is transferred from the moving cart to the box.

Front

What happens to friction when the weight of an object increases?

Back

Friction generally increases when the weight of an object increases, especially on rough surfaces.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object to another.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from potential to kinetic energy.
