2. Mass: A measure of the amount of matter in an object, usually measured in kilograms (kg).
3. Weight: The force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).
4. Energy: The capacity to do work, which can exist in various forms such as kinetic, potential, thermal, and chemical energy.
5. Kinetic Energy: The energy possessed by an object due to its motion, calculated using the formula KE = 1/2 mv^2, where m is mass and v is velocity.
6. Potential Energy: The energy stored in an object due to its position or configuration, often associated with gravitational or elastic forces.
7. Work: The energy transferred to or from an object via the application of force along a displacement, calculated as W = Fd cos(θ), where F is force, d is displacement, and θ is the angle between the force and displacement vectors.
