Physics Final Exam Review

Front

Does mass differ from weight?

Back

Yes, mass and weight are very different. Mass is a measure of the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What does the work-energy theorem state?

Back

The work-energy theorem relates the work done by all forces to the change in kinetic energy of an object.

Front

What happens if a net (unbalanced) force is applied to an object?

Back

The object accelerates.

Front

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force exerted by a machine to the input force applied to it.

Front

What is the horizontal component of a projectile’s velocity?

Back

The horizontal component of a projectile’s velocity remains unchanged the entire time.

Front

Define mass.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

Define weight.

Back

Weight is the force exerted on an object due to gravity, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or configuration, commonly gravitational potential energy given by PE = mgh.
