Energy - Vocabulary

Front

Can an object have both potential energy and kinetic energy at the same time?

Back

True

Front

What is the definition of a Watt?

Back

A Watt is defined as one Joule per second (\(\frac{J}{s}\)).

Front

What is the definition of a Joule?

Back

A Joule is defined as a Newton meter (\(N \cdot m\)).

Front

What does the law of conservation of energy state?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

How do you calculate Power?

Back

Power is calculated using the formula \(P = \frac{W}{t}\), where \(W\) is work and \(t\) is time.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy is \(KE = \frac{1}{2}mv^2\), where \(m\) is mass and \(v\) is velocity.

Front

What is the formula for calculating potential energy?

Back

The formula for gravitational potential energy is \(PE = mgh\), where \(m\) is mass, \(g\) is acceleration due to gravity, and \(h\) is height.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.
