Match the following concepts with their definitions related to projectile motion:

Range = The maximum horizontal distance traveled by the projectile Height = The maximum vertical distance reached by the projectile above its initial height Time of Flight = The time taken by the projectile to reach the ground from its maximum height Apex = The highest point reached by the projectile

Match the following types of energy with their descriptions:

Kinetic Energy = Energy of motion Potential Energy = Energy stored in an object due to its position or state Thermal Energy = Energy of heat Electrical Energy = Energy associated with the movement of charged particles

Match the following equations with their corresponding physical quantities:

mgh = Potential Energy (1/2)mv^2 = Kinetic Energy mgh + (1/2)mv^2 = Total Mechanical Energy v = u + at = Equation of motion
