What is a scalar?

Back

A scalar is a quantity that has magnitude but no direction.

Front

What is the potential energy (PE) and kinetic energy (KE) at the lowest point of a roller coaster?

Back

At the lowest point, the potential energy is at a minimum and the kinetic energy is at a maximum.

Front

What is the speed of an object that has not moved after 3 hours?

Back

The speed is 0 mi/hr.

Front

Which subatomic particle carries a positive charge?

Back

Protons carry a positive charge.

Front

Who moved the fastest in a 3-second race: biker, runner, or walker?

Back

The biker moved the fastest.

Front

What is the definition of kinetic energy?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is potential energy?

Back

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

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).
