Physics Semester Final Review

Front

What is a vector? Give two examples.

Back

A vector is a quantity that has both magnitude and direction. Two examples of vectors are displacement and velocity.

Front

What is the unit for displacement?

Back

The unit for displacement is meter (m).

Front

What happens if two objects of different masses fall in a vacuum?

Back

Both objects will fall at the same rate in a vacuum.

Front

What happens if two objects of different masses fall in a tube with air resistance?

Back

The heavier object will fall faster in a tube with air resistance.

Front

What is Newton's 3rd Law?

Back

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

Front

What is instantaneous speed?

Back

The speed of an object at a specific point in time.

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.

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.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = m * g * h.
