What is Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

What happens to the velocity of a ball as it is dropped off a cliff?

Back

The velocity of the ball increases at a uniform rate due to the acceleration of gravity.

Front

What is the SI unit for acceleration?

Back

The SI unit for acceleration is meters per second squared (m/s²).

Front

What is the formula to calculate speed?

Back

The formula to calculate speed is S = d/t, where S is speed, d is distance, and t is time.

Front

What is velocity?

Back

Velocity is defined as speed in a specific direction.

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 the formula for calculating distance?

Back

The formula for calculating distance is d = S x t, where d is distance, S is speed, and t is time.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

What is the difference between instantaneous speed and average speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time, while average speed is the total distance traveled divided by the total time taken.
