Potential and KInetic

Front

What is the definition of KINETIC energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the definition of POTENTIAL energy?

Back

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

Front

Give an example of KINETIC energy.

Back

A football thrown and released into the air.

Front

Give an example of POTENTIAL energy.

Back

A book on the top shelf.

Front

What factors affect KINETIC energy?

Back

Kinetic energy depends on the mass of the object and the square of its velocity (KE = 1/2 mv^2).

Front

What factors affect POTENTIAL energy?

Back

Potential energy depends on the mass of the object, the height above a reference point, and the gravitational force (PE = mgh).

Front

How is KINETIC energy calculated?

Back

Kinetic energy is calculated using the formula KE = 1/2 mv^2, where m is mass and v is velocity.

Front

How is POTENTIAL energy calculated?

Back

Potential energy is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the relationship between KINETIC and POTENTIAL energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, assuming no external forces do work.

Front

What happens to POTENTIAL energy as an object falls?

Back

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