Physics Semester 1 Final Exam Review - long

Front

What does a graph with a straight line represent in motion?

Back

Constant Speed

Front

How do you calculate Gravitational Potential Energy (G.P.E.)?

Back

G.P.E. = mass (kg) × gravitational acceleration (9.8 m/s²) × height (m)

Front

What does a scale measure when a person stands on it?

Back

The gravitational force acting on the person (weight)

Front

At which point in a roller coaster is potential energy greatest?

Back

At the highest point of the track

Front

What type of energy is stored in an object due to its position?

Back

Potential Energy

Front

What is the formula for Kinetic Energy?

Back

K.E. = 1/2 × mass (kg) × velocity² (m/s)²

Front

What happens to the potential energy of an object as it falls?

Back

It decreases as kinetic energy increases.

Front

What is the relationship between mass and weight?

Back

Weight = mass × gravitational acceleration (9.8 m/s²)

Front

What type of energy is associated with motion?

Back

Kinetic Energy

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J)
