Question 1:
Which of the following quantities represents the energy of an object due to its motion?
Explanation: The correct answer is C) Kinetic energy. The kinetic energy of an object represents the energy it possesses due to its motion. It depends on the mass of the object and its velocity.
Question 2:
Which of the following factors affects the kinetic energy of an object?
Explanation: The correct answer is C) Both mass and velocity. The kinetic energy of an object depends on both its mass and velocity. Increasing either the mass or the velocity of the object will result in an increase in its kinetic energy.
Question 3:
Which of the following quantities represents the energy stored in an object due to its position or condition?
Explanation: The correct answer is D) Potential energy. Potential energy is the energy stored in an object due to its position or condition. It depends on factors such as height, elastic deformation, or chemical composition.
Question 4:
Which of the following factors affects the potential energy of an object in a gravitational field?
Explanation: The correct answer is C) Both mass and height. The potential energy of an object in a gravitational field depends on both its mass and the height at which it is located. Increasing either the mass or the height will result in an increase in the object's potential energy.
Question 5:
Which type of potential energy is associated with the stretching or compressing of an elastic object?
Explanation: The correct answer is C) Elastic potential energy. Elastic potential energy is associated with the stretching or compressing of an elastic object, such as a spring or a rubber band. It represents the potential for the object to return to its original shape or position.
