Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

The rate of change of velocity of an object, measured in m/s².

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is the formula for kinetic energy?

Back

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

Front

What is gravitational force?

Back

The attractive force between two masses, proportional to their masses and inversely proportional to the square of the distance between them.
