Science (Module 2) Mid-Module Test Review

Front

What is a ramp?

Back

A ramp is a sloped surface that connects two different heights, allowing objects to move from one level to another more easily.

Front

Which ramp will give a car greater speed, a steep ramp or a flat ramp?

Back

A steep ramp will give the car greater speed because it allows the car to gain more height and potential energy.

Front

What happens when two bumper cars collide?

Back

When one bumper car collides with another, the force from the collision can cause both cars to move.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the wind, which can be converted into electricity using wind turbines.

Front

What do wind turbines do?

Back

Wind turbines convert the kinetic energy of wind into mechanical energy, which can then be used to generate electricity.

Front

What is an open circuit?

Back

An open circuit is a type of electrical circuit where the path is broken, preventing current from flowing.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit that allows current to flow without interruption.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one place to another, such as from the sun to plants.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a car at the top of a ramp.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, such as a car rolling down a ramp.
