Kinetic and Potential Energy

Front

What is the definition of weight?

Back

Weight is the force exerted by gravity on an object, measured in Newtons.

Front

What is the manipulated variable in an experiment?

Back

The manipulated variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

How is potential energy defined?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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

How does mass affect potential energy?

Back

Potential energy increases with mass; the greater the mass of an object at a height, the greater its potential energy.

Front

What is the relationship between velocity and kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

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 is the unit of measurement for energy?

Back

The unit of measurement for energy is the Joule (J).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object possesses due to its height in a gravitational field.
