Kinematics Review

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

Define speed.

Back

Speed is a scalar quantity that refers to how fast an object is moving, measured as distance traveled per unit of time.

Front

Define velocity.

Back

Velocity is a vector quantity that refers to the speed of an object in a specific direction.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).

Front

What does it mean for an object to be in uniform motion?

Back

An object is in uniform motion if it travels equal distances in equal intervals of time, maintaining a constant speed.

Front

What is the significance of a velocity-time graph?

Back

A velocity-time graph shows how the velocity of an object changes over time, allowing us to determine acceleration and displacement.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line on a distance-time graph indicates that the object is at rest and not moving.

Front

How do you calculate acceleration?

Back

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