PEC Science Formula Review Flashcard

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is a scalar quantity.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the formula for potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the SI unit for potential energy?

Back

The SI unit for potential energy is Joules (J).

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time.

Front

What is the SI unit for mass?

Back

The SI unit for mass is Kilogram (kg).

Front

What is the SI unit for work?

Back

The SI unit for work is Joule (J).

Front

What is the formula for calculating work done?

Back

Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically relative to the ground.

Front

What is the formula for calculating average velocity?

Back

Average Velocity = Displacement / Time.
