Energy Transformations

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

How does potential energy change as an object moves up a ramp?

Back

As an object moves up a ramp, its potential energy increases while its kinetic energy decreases.

Front

What is the relationship between potential energy and mechanical energy?

Back

The total mechanical energy of an object is the sum of its potential energy and kinetic energy.

Front

What happens to the energy of a toy car as it travels up a ramp?

Back

The toy car's potential energy increases while its kinetic energy decreases.

Front

At which position does an object have the highest potential energy on a ramp?

Back

An object has the highest potential energy at the highest point on the ramp.

Front

Is it true that a ball's potential energy is equal to its mechanical energy at the highest point?

Back

True, at the highest point, the ball's potential energy is equal to its total mechanical energy if we neglect air resistance and friction.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does energy transform as a cart goes down a hill?

Back

As the cart goes down a hill, its potential energy decreases while its kinetic energy increases.

Front

What factors affect the amount of potential energy an object has?

Back

The amount of potential energy an object has depends on its mass, height above the ground, and the gravitational force acting on it.
