Work, Power, and Energy Flashcard

Front

What is the formula for mechanical advantage in terms of distance?

Back

Input distance / Output distance

Front

How do machines increase an output force?

Back

By changing the distance over which the force is applied

Front

What is the SI unit for power?

Back

Watt (W)

Front

In the formula P = W/t, what does 'P' stand for?

Back

Power

Front

If a force of 5200 N is applied over a distance of 25 m, how much work is done?

Back

130000 J

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) x Distance (d)

Front

What is the relationship between work, power, and time?

Back

Power (P) = Work (W) / Time (t)

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration.
