Read each question carefully and provide detailed answers or calculations where required. Show all your work for numerical problems.
1. Which of the following best defines kinetic energy?
Energy possessed by an object due to its position.
Energy possessed by an object due to its motion.
Energy stored in a chemical bond.
Energy transferred due to temperature difference.
2. If the velocity of an object doubles, its kinetic energy will:
Double
Halve
Quadruple
Remain the same
3. The formula for kinetic energy is KE = .
4. Kinetic energy is a quantity, meaning it has magnitude but no direction.
5. A car with a mass of 1200 kg is traveling at a speed of 25 m/s. Calculate its kinetic energy.
6. Explain the Work-Energy Theorem and how it relates to kinetic energy.
7. An object at rest possesses kinetic energy.
True
False
8. Kinetic energy can be negative.
True
False
9. A 50 kg object is initially moving at 10 m/s. A constant force then acts on it, increasing its speed to 20 m/s. Calculate the work done by the net force on the object.
