Front

Define displacement in physics.

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time

Front

Explain the concept of free fall.

Back

Free fall is the motion of an object under the influence of gravitational force only, with no air resistance.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
