Physical Science - 2nd Nine Weeks Semester Exam Review

Front

What is gravitational potential energy (GPE)?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

What does the 3rd law of motion state?

Back

The 3rd law of motion states that for every action, there is an equal and opposite reaction.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a wave's medium move from their rest position.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

How does height affect gravitational potential energy?

Back

The higher an object is, the more gravitational potential energy it has due to its position in the gravitational field.

Front

What is the formula for calculating net force?

Back

Net force = mass x acceleration (F = ma).
