Physics Honors Final Exam

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Wavelength × Frequency

Front

What determines the time a projectile remains in flight?

Back

The initial velocity of the projectile.

Front

State Newton's Third Law of Motion.

Back

For every action, there is an equal and opposite reaction.

Front

How is potential energy stored in a spring calculated?

Back

Potential Energy = 0.5 × k × x², where k is the spring constant and x is the displacement.

Front

What happens to lightbulbs in a series circuit if there is a break?

Back

If there is a break, all lightbulbs will not work.

Front

What is the relationship between frequency and wavelength in wave motion?

Back

Frequency is inversely proportional to wavelength; as frequency increases, wavelength decreases.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 0.5 × m × v².

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

Explain the concept of centripetal force.

Back

Centripetal force is the net force causing the inward acceleration of an object moving in a circular path.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational Potential Energy = m × g × h, where m is mass, g is acceleration due to gravity, and h is height.
