Lesson Worksheet: Kinetic Energy Science
In this worksheet, we will practice determining the energy for an object due to motion of the object.
Q1:
A blue ball and a green ball move the same distance in a straight line for the same amount of time. The green ball has a greater mass. Which of the following correctly relates the kinetic energies for the balls?
- AThe kinetic energy for the blue ball is greater.
- BThe kinetic energy for the green ball is greater.
- CThe kinetic energy is the same for both balls.
Q2:
A blue ball and a green ball have the same mass. Each ball moves in a straight line for the same amount of time, but the blue ball moves further. Which of the following correctly relates the kinetic energies for the balls?
- AThe kinetic energy is the same for both balls.
- BThe kinetic energy for the blue ball is greater.
- CThe kinetic energy for the green ball is greater.
Q3:
What would increase the kinetic energy of an object more, doubling the mass of the object or doubling the velocity of the object?
- ADoubling the mass
- BDoubling the velocity
- CBoth changes would increase the kinetic energy equally.
Q4:
An object that is moving decreases in velocity. Which of the following correctly describes how the kinetic energy changes for the object?
- AThe kinetic energy does not change.
- BThe kinetic energy increases.
- CThe kinetic energy decreases.
Q5:
An object that is moving increases in velocity. Which of the following correctly describes how the object’s kinetic energy changes?
- AThe kinetic energy decreases.
- BThe kinetic energy increases.
- CThe kinetic energy does not change.
Q6:

Q7:
An object has a mass of 8 kg and a velocity of 2 m/s. The velocity of the object increases to 3 m/s. Find the increase in kinetic energy.
Q8:

- A
- B
Q9:
What is the kinetic energy of an object with a mass of 1 kg and a speed of 1 m/s?
Q10:
