Front

What is the formula to calculate net force?

Back

Net Force = Applied Force - Frictional Force

Front

How does gravitational force change with distance?

Back

Gravitational force decreases with the square of the distance between two objects.

Front

What happens to the total mechanical energy of a free-falling object without air resistance?

Back

The total mechanical energy remains constant.

Front

What is the formula to calculate the distance an object travels horizontally while falling?

Back

Distance = Horizontal Velocity x Time of Fall

Front

What is the formula for gravitational force between two masses?

Back

Gravitational Force = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What is the effect of doubling the distance on gravitational force?

Back

The gravitational force is reduced by a factor of 4.

Front

What is kinetic energy?

Back

Kinetic Energy = 1/2 * mass * velocity^2.

Front

What is potential energy?

Back

Potential Energy = mass * gravity * height.

Front

What is the relationship between kinetic energy and potential energy in free fall?

Back

As potential energy decreases, kinetic energy increases, keeping total mechanical energy constant.

Front

What is the significance of air resistance in free fall?

Back

Air resistance opposes the motion and reduces the acceleration of falling objects.
