Ruiz - Work Power and Energy Review

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is kinetic energy?

Back

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

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy stored in an object as it has the potential to fall due to gravity.

Front

At which position does a pendulum have the greatest gravitational potential energy?

Back

At the highest point of its swing.

Front

What is the definition of work in physics?

Back

Work is done when a force causes an object to move. It is calculated as W = Fd, where F is force and d is distance.

Front

How do you calculate work done when a force is applied?

Back

W = Fd, where W is work, F is force, and d is distance.

Front

What is the fixed point on a lever called?

Back

Fulcrum.

Front

What type of energy is stored energy?

Back

Potential energy.

Front

If a force of 200 N is applied over a distance of 426 meters, how much work is done?

Back

85,200 J.
