What is the definition of free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no air resistance.

Front

What is the formula for momentum?

Back

Momentum (p) is defined as the product of an object's mass (m) and its velocity (v): p = m * v.

Front

What is the relationship between net force and acceleration according to Newton's second law?

Back

The net force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a): F = m * a.

Front

What happens to potential energy when an object is lifted against gravity?

Back

The potential energy of an object increases as it is lifted against gravity, calculated as PE = m * g * h, where g is the acceleration due to gravity and h is the height.

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed in a circular path, where the direction of the velocity vector is continuously changing.

Front

How do you calculate the acceleration of an object?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the significance of a velocity vs. time graph?

Back

A velocity vs. time graph shows how an object's velocity changes over time; the slope of the graph represents acceleration.

Front

What is the concept of kinetic energy?

Back

Kinetic energy (KE) is the energy of an object due to its motion, calculated as KE = 1/2 * m * v^2.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
