AP 1 Energy with Springs

Front

What does the area under the curve on a conservative force versus displacement graph represent?

Back

The area under the curve represents both the work done on an object and the change in energy for that object, according to the work-energy theorem.

Front

Define potential energy.

Back

Potential energy is the energy an object has due to its position or condition.

Front

If a 0.5 kg ball is thrown up with 250 J of kinetic energy, how high will it go?

Back

51 m

Front

What quantity can you calculate from a graph that gives the magnitude of that quantity?

Back

Spring constant 20 N/m

Front

What is the energy of a certain point with respect to some reference point called?

Back

Potential Energy

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv²

Front

What is the formula for potential energy?

Back

PE = mgh

Front

What does 'g' represent in the potential energy formula?

Back

'g' represents the acceleration due to gravity, approximately 9.8 m/s².

Front

What is the relationship between work and energy according to the work-energy theorem?

Back

Work done on an object is equal to the change in energy of that object.

Front

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

Back

The unit of energy is the Joule (J).
