Back

TRUE

Front

What is the formula for calculating gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv^2.

Front

What is the principle of conservation of energy?

Back

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 moves, while velocity is a vector quantity that includes direction.

Front

What is Newton's second law of motion?

Back

F = ma, where F is the force, m is the mass, and a is the acceleration.
