Amplify Magnetic Fields Chapter 2

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What factors affect potential energy?

Back

Potential energy depends on the object's mass, height above the ground, and the gravitational force acting on it.

Front

What is kinetic energy?

Back

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

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is elastic force?

Back

Elastic force is the force exerted by a material when it is stretched or compressed, returning to its original shape.

Front

How does distance affect gravitational potential energy?

Back

The greater the height (distance) of an object from the ground, the more gravitational potential energy it has.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with mass; a heavier object moving at the same speed has more kinetic energy than a lighter object.

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.
