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 the formula for calculating distance when an object is accelerating?

Back

Distance (d) = initial velocity (u) * time (t) + 0.5 * acceleration (a) * time (t)^2.

Front

Define 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 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 happens to the velocity of an object in free fall?

Back

In the absence of air resistance, the velocity of an object in free fall increases at a constant rate due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How do you calculate the final velocity of an object under constant acceleration?

Back

Final velocity (v) = initial velocity (u) + acceleration (a) * time (t).

Front

What is a position-time graph?

Back

A position-time graph shows how the position of an object changes over time, with position on the y-axis and time on the x-axis.

Front

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

Back

A horizontal line indicates that the object is at rest, as its position does not change over time.
