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 acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²).

Front

What is the formula for calculating final velocity?

Back

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

Front

What does a zero displacement mean?

Back

Zero displacement means that an object has returned to its original position, regardless of the distance it has traveled.

Front

Explain the significance of the highest point in a projectile's motion.

Back

At the highest point of a projectile's motion, the velocity is zero, but the acceleration due to gravity is still acting on the object, pulling it downward.

Front

What is a motion diagram?

Back

A motion diagram is a visual representation of an object's position at equal time intervals, showing how the object's position changes over time.

Front

What does a positive acceleration indicate?

Back

Positive acceleration indicates that an object's velocity is increasing over time.

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 is the formula for calculating displacement?

Back

Displacement can be calculated using the formula: Displacement = Final position - Initial position.

Front

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

Back

A flat line on a velocity-time graph indicates that the object is moving at a constant velocity.
