Front

How do you calculate the density of an object?

Back

Density = Mass / Volume

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the principle of conservation of energy?

Back

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

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion, calculated as KE = 1/2 mv^2.

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration, calculated as PE = mgh.
