Explanation

A car's steering system uses a wheel and axle.

It is mechanism to transmit the rotational motion of the steering wheel to the wheels of the car, allowing the vehicle to turn.

Explanation

• Cranes use movable pulleys to lift and move heavy loads.
• The pulleys are attached to a cable or rope that wraps around a drum or wheel.
• It allowing the load to be lifted or moved in a vertical direction.

Explanation

A movable pulley decreases the amount of input force needed to lift a load.

By allowing the user to apply force over a longer distance.

Explanation

• Renewable sources, such as solar energy, wind energy, hydro energy, and biomass, are sustainable and can be replenished naturally.
• They can be used over and over again, making them virtually unlimited.

Explanation

• Non-renewable sources, such as fossil fuels (coal, oil, and gas), nuclear energy, and minerals.
• They are limited in supply and cannot be replenished in a short period of time.
• Once they are used, they are gone forever.

Explanation

• The fuel (gasoline or diesel) in a car is a form of chemical energy, which is stored in the bonds of the fuel molecules.
• When the fuel is burned in the engine, this chemical energy is converted into kinetic energy (the energy of motion) through a series of processes, including combustion, transmission, and propulsion.

Explanation

• When Hyder hits the nail with a hammer, kinetic energy (the energy of motion) is involved as the hammer moves towards the nail.
• Sound energy is also involved as the hammer strikes the nail, producing a sound.
• However, electrical energy is not involved in this process.

Explanation

• The batteries in the toy car store chemical energy.
• It is converted into electrical energy when the batteries are connected to the toy car's motor.

Explanation

• Kinetic energy is the energy of motion.
• It is the energy an object possesses when it is in motion, such as a rolling ball, a moving car, or a flying bird.
• The amount of kinetic energy an object has depends on its mass and velocity.

Explanation

• Thermal energy is the form of energy that is transferred from one body to another due to a difference in temperature, and is received from heat.
• It is the energy of motion of particles in a substance, such as atoms or molecules, and is often referred to as "heat energy".
