Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its speed.

Front

How does potential energy change during a descent?

Back

As an object descends, 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 depends on the object's mass and its height above a reference point.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) can be 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 the potential energy of a rock at the edge of a cliff?

Back

The rock has maximum potential energy at the edge of the cliff due to its height.

Front

What is the relationship between speed and kinetic energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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

Front

Can potential energy be converted to kinetic energy?

Back

Yes, potential energy can be converted to kinetic energy, such as when an object falls.

Front

What is an example of potential energy in everyday life?

Back

A drawn bow has potential energy due to the tension in the string.
