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

Define displacement.

Back

Displacement is the vector quantity that represents the change in position of an object, measured from the initial to the final position.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that measures the total path length traveled, while displacement is a vector quantity that measures the shortest straight-line distance from the initial to the final position.

Front

What is velocity?

Back

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

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity with respect to time, and it can be positive (speeding up) or negative (slowing down).

Front

What is constant acceleration?

Back

Constant acceleration occurs when an object's velocity changes at a consistent rate over time.

Front

How do you calculate final velocity with constant acceleration?

Back

Final velocity (v) can be calculated using the formula: v = u + at, where u is the initial velocity, a is the acceleration, and t is the time.

Front

What is a motion diagram?

Back

A motion diagram is a visual representation of an object's position at equal time intervals, often using dots to indicate the object's location over time.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how an object's velocity changes over time, where the slope represents acceleration.

Front

What does a horizontal line on a velocity-time graph indicate?

Back

A horizontal line on a velocity-time graph indicates constant velocity, meaning there is zero acceleration.
