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 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 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 does a positive velocity indicate?

Back

A positive velocity indicates that an object is moving in the positive direction of the chosen coordinate system.

Front

What does a negative velocity indicate?

Back

A negative velocity indicates that an object is moving in the negative direction of the chosen coordinate system.

Front

What does it mean when an object is slowing down?

Back

When an object is slowing down, its acceleration is in the opposite direction to its velocity.

Front

What does it mean when an object is speeding up?

Back

When an object is speeding up, its acceleration is in the same direction as its velocity.

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 does a flat line on a velocity-time graph represent?

Back

A flat line on a velocity-time graph represents constant velocity, meaning the object is moving at a steady speed.
