Front

Define 'velocity'.

Back

Velocity is the rate of change of displacement with respect to time, including direction.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity representing the total path length, while displacement is a vector quantity representing the shortest path from the initial to the final position.

Front

What is the formula for calculating work?

Back

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

Front

What is the SI unit for force?

Back

Newtons (N)

Front

Define 'acceleration'.

Back

Acceleration is the rate of change of velocity with respect to time.
