1. The answer to this question will depend on the specific questions asked on the test. It is important to review the test questions and provide accurate answers based on your knowledge of physics concepts.
2. Work is done when a force is applied to an object and the object moves in the direction of the force.
3. The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another.
4. Power is the rate at which work is done or energy is transferred. It is measured in watts (W).
5. The formula for calculating work is W = Fd cosθ, where F is the force applied, d is the distance the object moves, and θ is the angle between the force and the direction of motion.
6. Kinetic energy is the energy an object possesses due to its motion, and is calculated using the formula KE = 0.5mv^2, where m is the mass of the object and v is its velocity.
7. Potential energy is the energy an object possesses due to its position or configuration, and is calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above a reference point.
8. The conservation of mechanical energy states that the total mechanical energy of a system (the sum of kinetic and potential energy) remains constant as long as only conservative forces are acting on the system.
9. The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy, or W = ΔKE.
10. Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, or a = F/m.
