Kinematics

Front

What is Kinematics?

Back

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

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

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that refers to how much ground an object has covered, while displacement is a vector quantity that refers to how far out of place an object is.

Front

What is velocity?

Back

Velocity is the rate of change of displacement with respect to time, and it includes both speed and direction.

Front

What is acceleration?

Back

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

Front

What is uniform motion?

Back

Uniform motion occurs when an object travels equal distances in equal intervals of time.

Front

What is non-uniform motion?

Back

Non-uniform motion occurs when an object travels unequal distances in equal intervals of time.

Front

What is the formula for calculating average velocity?

Back

Average velocity = Total displacement / Total time taken.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.81 m/s² near the surface of the Earth.
