Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m)

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.

Front

How do you calculate acceleration when given initial and final velocities and distance?

Back

Use the formula: a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

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

Back

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

Front

What is the formula for calculating net force?

Back

Net Force (F) = Mass (m) x Acceleration (a)

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does it mean for an object to be in free fall?

Back

An object in free fall is only under the influence of gravity, with no air resistance.

Front

How do you determine the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circular path.

Front

What is the formula for calculating the change in velocity?

Back

Change in Velocity (Δv) = Final Velocity (v_f) - Initial Velocity (v_i)
