Review: 1st Semester Physics

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is greatest at the highest point of a pendulum's swing.

Front

At which point in a pendulum's swing is potential energy at its greatest?

Back

At the highest point of the swing.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is an example of Newton's 1st Law of Motion?

Back

A magician pulling a tablecloth from under dishes without moving the dishes.

Front

What is the variable letter for range in physics?

Back

X

Front

What is the SI unit for length or distance?

Back

Meter (m) is the SI unit for length.

Front

What is the variable letter for horizontal velocity?

Back

V_x represents horizontal velocity.

Front

What is the formula for calculating potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is the relationship between potential energy and kinetic energy in a pendulum?

Back

As a pendulum swings, potential energy converts to kinetic energy and vice versa, conserving total mechanical energy.
