Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v_f) - Initial Velocity (v_i)) / Time (t)

Front

What happens to the total mechanical energy of an object in free fall without air resistance?

Back

The total mechanical energy remains the same.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

Front

How can you identify a segment with no acceleration on a graph?

Back

A segment with no acceleration is represented by a horizontal line on a velocity-time graph.

Front

What is the formula for gravitational force between two masses?

Back

Gravitational Force (F) = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

Define 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

Define potential energy.

Back

Potential energy (PE) is the energy stored in an object due to its position or configuration, commonly gravitational potential energy calculated as PE = m * g * h.

Front

What is the principle of conservation of energy?

Back

The principle 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.

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) * Acceleration (a).
