Energy and Heat Worksheet

Which statement correctly describes the relationship between energy and the way an object moves?

• An object has the most energy when it is not moving.

• The faster the speed of the object, the more energy it has.

• The slower the speed of the object, the more energy it has.

• An object has the most energy when it is moving back and forth.

Calculate the speed of a cannon ball that travels 500 km in 30 seconds. The formula has been provided to the right. Show all work, round your answer to the nearest tenth (0.1) and use correct units.

• Speed = 500 km / 30 s = 16.7 km/s

• Speed = 500 km / 30 s = 1.7 km/s

• Speed = 500 km / 30 s = 0.06 km/s

• Speed = 500 km / 30 s = 150 km/s

When a cannonball is fired, there is a loud noise when it leaves the cannon. The graphs below show the sound waves of 2 different cannonballs A and B that were fired. Note that an oscilloscope was used to convert a longitudinal sound wave into a transverse wave. Pirate Pete notices that cannonball B was louder than cannonball A. What is the best evidence from the graph that supports his claim?

• The amplitude of cannonball B is higher than the amplitude of cannonball A.

• The amplitude of cannonball B is lower than the amplitude of cannonball A.

• The wavelength of cannon ball A is shorter than then the wavelength of cannonball B.

• The wavelength of cannon ball A is longer than the wavelength of cannonball B.

Which statement best evaluates the student’s claim?

• The claim is incorrect because the potential energy increases when the speed of the ball increases.

• The claim is incorrect because the potential energy of the ball is being transferred to kinetic energy as it travels down the ramp.

• The claim is correct because the speed of the ball increases, causing the ball to remain in motion as it travels down the ramp.

• The claim is correct because the speed of the ball is the same as its kinetic energy, and the speed of the ball increases as it travels down the ramp.

Which statement best explains whether the student’s statement is correct or incorrect?

• The statement is correct because the gravitational force acting on the objects with different masses is the same.

• The statement is incorrect because an object with more mass has more potential energy.

• The statement is incorrect because more force is needed to lift an object with more mass to the same height as an object with less mass.

• The statement is correct because the potential energy of any object with mass is based on an object’s height above the ground and the speed at which it travels.
