Kinetic and Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion, 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 energy stored in an object due to its position or configuration, commonly calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does mass affect kinetic energy?

Back

Increasing an object's mass will increase its kinetic energy, as kinetic energy is directly proportional to mass.

Front

How does velocity affect kinetic energy?

Back

Kinetic energy increases with the square of the velocity; thus, if the velocity doubles, the kinetic energy increases by a factor of four.

Front

At what point is potential energy greatest in a gravitational field?

Back

Potential energy is greatest at the highest point in a gravitational field, where the height (h) is maximized.

Front

At what point is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point in a gravitational field, where the object has the highest speed.

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 the speed.

Front

Where is kinetic energy least for an object in motion?

Back

Kinetic energy is least when the object is at rest or at its highest point in a gravitational field, where its speed is minimal.

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 can potential energy be converted to kinetic energy?

Back

Potential energy can be converted to kinetic energy when an object falls or moves downward in a gravitational field.
