Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

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

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

How is Kinetic Energy calculated?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

How is Potential Energy calculated?

Back

Gravitational potential energy (PE) is calculated using the formula: PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is an example of Kinetic Energy?

Back

A moving car is an example of kinetic energy, as it is in motion.

Front

What is an example of Potential Energy?

Back

A stretched rubber band is an example of potential energy, as it has stored energy due to its position.

Front

What type of energy is involved when a bow is drawn back?

Back

The energy involved is potential energy, as the bow stores energy when drawn back.

Front

What is the relationship between Kinetic and Potential Energy in a hydroelectric dam?

Back

In a hydroelectric dam, water's potential energy is converted into kinetic energy as it flows, which is then transformed into electrical energy.

Front

At which point does an object have the greatest Kinetic Energy?

Back

An object has the greatest kinetic energy at the lowest point of its fall, where its speed is highest.
