According to Boyle’s Law, at constant temperature, the pressure of a gas increases when its volume decreases, as the particles are compressed into a smaller space.

A capacitor stores electrical energy in an electric field and can release it when needed. It is used for smoothing voltage fluctuations in circuits.

Light travels the slowest in glass because it has a higher refractive index compared to air or vacuum.

Elasticity is the property of a material to return to its original shape and size after being deformed, such as stretching or compressing.

A moving car has kinetic energy because it is in motion, and its energy is proportional to its mass and velocity.

During a rocket launch, thrust force generated by the rocket's engines is the primary force acting on the rocket, allowing it to overcome gravity and lift off the ground.

The wings of an airplane generate lift due to their shape (airfoil), which causes air to move faster over the top of the wing than underneath, creating lower pressure above and lifting the plane.

Helicopters can take off and land vertically by adjusting the pitch of their rotor blades, which allows them to generate the necessary lift without needing a runway.

Orbital rockets are designed to launch payloads such as satellites into space, reaching the required velocity to place them into orbit.

Aeroplanes typically use jet engines for high-speed propulsion, which operate on the principle of jet propulsion.
