Energy & Collisions

What happens when a fast-moving car hits a stopped car?

• The stopped car would cause more damage.

• Both cars would be equally damaged.

• The fast-moving car would cause more damage.

• The fast-moving car would stop immediately.

What is Sound Energy?

• Energy that is produced by vibrating sound waves.

• Energy that is produced by moving objects.

• Energy that is stored in chemical bonds.

• Energy that is generated by electrical currents.

What is an example of Kinetic Energy?

• A moving car has kinetic energy.

• A parked bicycle is an example.

• A rock at the top of a hill has kinetic energy.

• A book resting on a table has kinetic energy.

What is Energy Transformation?

• The process of creating energy from nothing.

• The conversion (change) of energy from one form to another.

• The ability to store energy indefinitely.

• The measurement of energy in joules.

What is the relationship between speed and damage in collisions?

• Higher speed generally results in more damage during a collision.

• Speed has no effect on damage during a collision.

• Lower speed causes more damage during a collision.

• Damage is only related to the weight of the vehicles involved.

What is an example of Energy Transfer?

• When heat moves from a hot object to a cooler one.

• When energy is stored in a battery.

• When a car accelerates due to fuel combustion.

• When light is reflected off a surface.

What is the difference between Kinetic and Potential Energy?

• Kinetic energy is energy of motion, while potential energy is stored energy.

• Kinetic energy is stored energy, while potential energy is energy of motion.

• Kinetic energy is the energy of an object at rest, while potential energy is the energy of an object in motion.

• Kinetic energy is the energy of an object in a gravitational field, while potential energy is the energy of an object in a magnetic field.

Why do your hands get warm when you rub them together?

• Some of the kinetic energy is converted to heat energy.

• Rubbing generates friction that cools the skin.

• The skin absorbs heat from the surrounding air.

• The movement increases blood circulation to the hands.

What is Potential Energy?

• The energy stored in an object due to its position or state.

• The energy of motion in an object.

• The energy released during a chemical reaction.

• The energy associated with the temperature of an object.

What happens to energy in a collision?

• Energy is destroyed during a collision.

• Energy is transferred and transformed during a collision.

• Energy remains unchanged during a collision.

• Energy is created from nothing during a collision.
