Kinematic Equations and Free Fall

Front

What is the definition of Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

What does the term 'Free Fall' mean?

Back

Free fall is the motion of a body where gravity is the only force acting upon it.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

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 acceleration?

Back

Acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t).

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line with a positive slope on a distance-time graph.

Front

What is the formula for distance traveled under constant acceleration?

Back

Distance (s) = Initial velocity (u) * Time (t) + 0.5 * Acceleration (a) * Time^2.

Front

How do you calculate the final velocity of an object in free fall?

Back

Final velocity (v) = Initial velocity (u) + (Acceleration due to gravity (g) * Time (t)).

Front

What is the value of acceleration due to gravity on Earth?

Back

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

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.
