Kinetic and Potential Energy

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

What is the formula for calculating gravitational potential energy (GPE)?

Back

GPE = m * g * h, where m is mass in kilograms, g is the acceleration due to gravity (9.8 m/s²), and h is height in meters.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 0.5 * m * v², where m is mass in kilograms and v is velocity in meters per second.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy due to the increased gravitational force acting on it.

Front

What is the relationship between kinetic energy and speed?

Back

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

Front

What type of energy is stored in food?

Back

Chemical energy is stored in food and can be transformed into other forms of energy when consumed.

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

What is an example of potential energy being converted to kinetic energy?

Back

A ball rolling down a hill converts its potential energy at the top into kinetic energy as it moves down.

Front

What factors affect the gravitational potential energy of an object?

Back

The gravitational potential energy of an object is affected by its mass, the height above the ground, and the acceleration due to gravity.
