Factors that Affect Kinetic Energy
⦁ Define:
⦁ Mass:
⦁ Speed:
⦁ Increasing an object’s speed will (Increase/Decrease/Have no effect) on its kinetic energy. (Highlight the correct answer.
⦁ When the mass of an object increases, the kinetic energy will (Increase/Decrease). (Highlight the correct answer).
Predicting Changes in Kinetic Energy
⦁ What are the two factors that affect kinetic energy?
⦁ If a bus and a car are traveling at the same speed
⦁ Which one has a higher kinetic energy?
⦁ How do you know?
⦁ Energy: The ability to do work or cause change.
⦁ Kinetic Energy: The energy an object possesses due to its motion.
⦁ Law of Conservation of Energy: Energy cannot be created or destroyed, only transferred or transformed.
⦁ Potential Energy: The energy an object has due to its position or condition.
⦁ Example of an object with kinetic energy: A moving car.
⦁ Example of an object with potential energy: A ball held at the top of a hill.
⦁ If the kinetic energy of an object increases as it falls to the ground, its potential energy decreases.
Factors that Affect Kinetic Energy
⦁ Mass: The amount of matter in an object.
⦁ Speed: The rate at which an object moves.
⦁ Increasing an object’s speed will Increase its kinetic energy.
⦁ When the mass of an object increases, the kinetic energy will Increase.
Predicting Changes in Kinetic Energy
⦁ The two factors that affect kinetic energy are mass and speed.
⦁ If a bus and a car are traveling at the same speed, the bus has a higher kinetic energy because of its greater mass.
⦁ This is because kinetic energy is directly proportional to both mass and the square of speed, so the bus with more mass will have higher kinetic energy even if both objects are moving at the same speed.
