What is a force?
A force is a measurement of speed.
A force is a type of energy.
A force is a fixed quantity that cannot change.
A force is an interaction that causes a change in motion.
Name one type of contact force.
Magnetism
Tension
Gravity
Friction
What is gravity?
Gravity is the temperature of an object in space.
Gravity is the speed at which objects fall.
Gravity is the force that attracts two bodies with mass towards each other.
Gravity is a type of energy that powers machines.
What is potential energy?
Potential energy is the energy of motion.
Potential energy is the energy stored in an object due to its position or configuration.
Potential energy is the energy associated with heat transfer.
Potential energy is the energy released during a chemical reaction.
What is kinetic energy?
Kinetic energy is the energy of an object in motion.
Kinetic energy is the energy stored in an object at rest.
Kinetic energy is the energy released during a chemical reaction.
Kinetic energy is the energy of an object due to its temperature.
What is the formula for work?
W = F / d
W = F - d
W = F × d × cos(θ)
W = F + d
How is work calculated?
Work = Mass × Acceleration
Work = Force + Distance
Work = Force × Distance × cos(θ)
Work = Energy × Time
What is mechanical energy?
Mechanical energy is the energy stored in chemical bonds.
Mechanical energy is only kinetic energy.
Mechanical energy is the energy of motion only.
Mechanical energy is the sum of potential and kinetic energy in a system.
What is thermal energy?
Thermal energy is the total kinetic energy of particles in a substance.
Thermal energy is the energy stored in chemical bonds.
Thermal energy is the energy produced by electrical currents.
Thermal energy is the energy associated with gravitational forces.
What is the difference between renewable and non-renewable energy?
Renewable energy is sustainable and replenishable, while non-renewable energy is finite and can be exhausted.
Renewable energy can only be used in specific locations.
Non-renewable energy sources are always cleaner than renewable sources.
Renewable energy is more expensive than non-renewable energy.
What is energy transfer?
Energy transfer refers to the destruction of energy.
Energy transfer is the creation of energy from nothing.
Energy transfer is the process of storing energy in one location.
Energy transfer is the movement of energy from one place or form to another.
How does energy transfer occur in a moving car?
Mechanical energy is converted back into fuel for the engine.
Energy transfer occurs only when the car is stationary.
Energy is transferred through the car's radio system.
Energy transfer in a moving car occurs through the conversion of fuel to mechanical energy, which propels the car forward via the wheels.
What is an example of energy being transformed?
A car running on gasoline.
A wind turbine spinning in the breeze.
A solar panel generating electricity.
A battery powering a flashlight.
What type of force is friction?
Friction is a contact force.
Friction is a gravitational force.
Friction is an electromagnetic force.
Friction is a non-contact force.
What is the unit of work?
pascal
joule
newton
watt
