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 velocity.

Back

Velocity is the rate of change of an object's position with respect to time, and it includes both speed and direction.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.

Front

What does a positive acceleration indicate when moving in a negative direction?

Back

A positive acceleration while moving in a negative direction means the object is slowing down.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph represents how an object's velocity changes over time.

Front

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

Back

A horizontal line on a velocity-time graph indicates constant velocity.

Front

What does a slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents acceleration.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the displacement of the object.

Front

What does it mean if an object has a negative velocity?

Back

A negative velocity indicates that the object is moving in the opposite direction to the defined positive direction.

Front

What is the formula for calculating average acceleration?

Back

Average acceleration is calculated using the formula: a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.
