Physics Final Exam Review

Front

What causes acceleration?

Back

Acceleration is caused by Force.

Front

What is the formula for gravitational force between two objects?

Back

F = G * (m1 * m2) / r², where G = 6.67 x 10⁻¹¹ N·m²/kg².

Front

What is the total mechanical energy (TME) when a rollercoaster is halfway down the track?

Back

TME = 50% GPE + 50% KE.

Front

What is impulse in physics?

Back

Impulse is the change in momentum.

Front

How do you calculate the period of a wave?

Back

Period (T) = Wavelength (λ) / Wave Speed (v).

Front

What is the relationship between speed, wavelength, and frequency?

Back

Wave Speed (v) = Wavelength (λ) * Frequency (f).

Front

What is kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * m * v², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational Potential Energy (GPE) = m * g * h, where g is acceleration due to gravity and h is height.

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 Newton's second law of motion?

Back

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