Front

What is displacement?

Back

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

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

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

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction.

Front

What is magnitude in physics?

Back

Magnitude refers to the size or quantity of a physical property, often represented as a numeric value.

Front

If a car accelerates at 2 m/s², how long will it take to reach a speed of 16 m/s from rest?

Back

It will take 8 seconds.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the unit of speed in the SI system?

Back

The unit of speed in the SI system is meters per second (m/s).
