Kinematics

Front

What is Kinematics?

Back

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

Front

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.
