Kinetic and Potential Energy Concepts Practice

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, an object at a height has gravitational potential energy.

Front

How does mass affect total energy?

Back

Increasing the mass of an object increases its total energy, as total energy is the sum of kinetic and potential energy.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, keeping the total energy constant.

Front

What is the relationship between kinetic energy and speed?

Back

The faster an object moves, the more kinetic energy it has, as kinetic energy is proportional to the square of its speed.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to particle movement when energy is added?

Back

When energy is added to a system, the particles move faster, increasing their kinetic energy.

Front

What is gravitational potential energy?

Back

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

Front

What is the effect of friction on kinetic energy?

Back

Friction converts kinetic energy into thermal energy, causing a decrease in the kinetic energy of moving objects.

Front

How can energy be transformed?

Back

Energy can be transformed from potential to kinetic energy and vice versa, such as in a swinging pendulum.
