Physics Final Exam

Front

What is the formula for calculating work done?

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 Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the definition of a satellite?

Back

A satellite is any object that is orbiting a planet, star, or other massive body.

Front

How do you calculate the distance traveled by an object moving at a constant speed?

Back

Distance = Speed × Time.

Front

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

Back

The unit of work is the Joule (J).

Front

What is the relationship between mass and acceleration when force is constant?

Back

As mass increases, acceleration decreases, according to Newton's 2nd Law.

Front

What does it mean when velocity is zero?

Back

When velocity is zero, the object is at rest or not moving.

Front

What is the formula for gravitational potential energy?

Back

Gravitational Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

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 difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
