Final answer:
The energy source that cars and trucks use to move is primarily gasoline in their tanks. Internal combustion engines burn the gasoline in the presence of oxygen to generate power, which propels the vehicle forward. While there are alternative energy sources like batteries and electric motors, the most common energy source for cars is gasoline.
Step-by-step explanation:
The energy source that cars and trucks use to move is primarily gasoline in their tanks. Gasoline is a fuel that is burned in an internal combustion engine, which generates power by burning the fuel in the presence of oxygen. This combustion produces a gas with high pressure that exerts force on a component, such as a piston, causing it to move and ultimately driving the vehicle forward.
While there are alternative energy sources for vehicles, such as batteries and electric motors (found in hybrid or electric cars) or solar panels (which can assist in generating electricity), the most common energy source for cars and trucks is still gasoline.
The other options mentioned in the question, such as air pressure in tires, falling water to generate electricity, rising steam to turn a turbine, or a parachute capturing air are not the primary energy sources for making cars and trucks move.
