What is renewable energy?
Energy derived from fossil fuels like coal and oil.
Energy that cannot be replaced once used, like nuclear energy.
Renewable energy is energy from sources that are naturally replenished, such as solar, wind, and hydro.
Energy generated from non-renewable sources such as natural gas.
Name two types of renewable energy sources.
Solar energy, Wind energy
Coal energy
Natural gas
Nuclear energy
What is the definition of force in physics?
Force is the weight of an object in a gravitational field.
Force is an interaction that causes a change in an object's motion.
Force is the speed of an object in motion.
Force is the amount of energy in an object.
List three types of forces.
centrifugal force
nuclear force
tension force
gravitational force, electromagnetic force, frictional force
What is gravitational force?
Gravitational force is the force that keeps objects in motion.
Gravitational force is the attraction between two masses.
Gravitational force is the repulsion between two masses.
Gravitational force is the energy produced by a mass.
How does gravity affect objects on Earth?
Gravity pulls objects toward the Earth, giving them weight and causing them to fall.
Gravity pushes objects away from the Earth, making them lighter.
Gravity has no effect on objects, allowing them to float freely.
Gravity only affects large objects, not small ones like pebbles.
What is the difference between contact and non-contact forces?
Contact forces are always stronger than non-contact forces.
Contact forces involve direct interaction; non-contact forces operate at a distance.
Contact forces can only occur in liquids and gases.
Non-contact forces require physical touch to act.
Give an example of a non-contact force.
Frictional force
Gravitational force
Magnetic force
Tension force
What role does renewable energy play in reducing carbon emissions?
Renewable energy increases carbon emissions by promoting industrial growth.
Renewable energy reduces carbon emissions by providing clean electricity that replaces fossil fuels.
Renewable energy has no impact on carbon emissions and is purely for economic gain.
Renewable energy only benefits urban areas and does not affect carbon emissions globally.
How does gravitational force vary with distance?
Gravitational force remains constant regardless of distance.
Gravitational force decreases with the square of the distance.
Gravitational force increases with distance.
Gravitational force varies linearly with distance.
