S432 Physics Set 1 Finals Review

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

How do you calculate the work done by a force?

Back

Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the relationship between power, work, and time?

Back

Power (P) = Work (W) / Time (t).

Front

What is the formula for impulse?

Back

Impulse (J) = Force (F) × Time (t).

Front

How do you calculate the final velocity of an object given its initial velocity, acceleration, and time?

Back

Final velocity (v) = Initial velocity (u) + (acceleration (a) × time (t)).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity (g) is approximately 10 m/s².

Front

What is the formula for calculating the distance fallen by an object in free fall?

Back

Distance (d) = 0.5 × g × t², where g is the acceleration due to gravity and t is the time in seconds.

Front

What is the definition of work in physics?

Back

Work is done when a force causes displacement of an object in the direction of the force.

Front

What is the principle of conservation of energy?

Back

The total energy in a closed system remains constant; energy can neither be created nor destroyed, only transformed.

Front

What is the unit of work and energy in the International System of Units (SI)?

Back

The unit of work and energy is the Joule (J).
