Physics First Semester Final Exam

Front

What is true of an object that is at rest?

Back

The object is experiencing a balance of forces.

Front

How is elastic potential energy calculated in a spring?

Back

Elastic potential energy (EPE) = 1/2 * k * x^2, where k is the spring constant and x is the displacement.

Front

What is the work done by a force?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What happens to an object's velocity when it experiences acceleration in the opposite direction?

Back

The object is slowing down.

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 gravitational potential energy formula?

Back

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

Front

What is the relationship between force, mass, and acceleration?

Back

Newton's Second Law states that Force = Mass x Acceleration (F = m * a).

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 the definition of friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.
