Semester Exam

Front

What does a graph showing no change in position over time represent?

Back

Not moving

Front

What happens to an object's acceleration when it slows down, goes faster, or changes direction?

Back

Acceleration occurs in all of the above scenarios.

Front

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

Back

W

Front

What does Newton's 1st law state?

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

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

Back

X

Front

Define acceleration in physics.

Back

Acceleration is the rate of change of velocity of an object.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is Newton's 2nd law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.
