Energy
What is different about potential energy and kinetic energy? Please provide an example
Potential energy does not move while kinetic energy is in motion
How is energy transferred by Sound? Please provide an example.
through vibrations that travel as waves
______________________ is the constant force around you. It cannot be created or destroyed.
Energy
True or False: When you pluck a guitar string, it vibrates and produces sound.
True
What are unbalanced forces? Please provide an example.
two forces of different strengths acting on an object.
How is energy transferred through electricity? Please provide an example.
through the movement of electric charges (electrons) in a circuit
For example, ______________________ is a measure of the rate of motion. It is how fast something travels.
Speed
True or False: Light energy does not moves from the source (flashlight or Sun) to another location, where it can illuminate or heat objects.
False
What are balanced forces? Please provide an example.
two forces, equal in strength, acting at the same time on an object to move it in
opposite directions.
How is energy transferred through light? Please provide an example.
light acts as a wave carrying energy from one place to another.
There are two types of energy. They are______________and__________________.
potential and kinetic
True or False: Heat moves from a warmer object to a warmer object.
False
What is the difference between inelastic collision and elastic collision? Please provide an example.
Inelastic-nvolves a change in energy. Kinetic energy will undergo a transfer as the objects
collide.
Elastic-the kinetic energy remains the same. The energy and movement are
conserved during impact.
How is energy transferred by heat? Please provide an example.
conduction, convection, and radiation
True or False: Electrical energy moves through wires and is transformed into other types of energy (light, heat).
True
What is a gravitational force? Please provide an example.
pulls two objects toward each other.
What is Newton's Third Law?
for every action force, there is an equal and opposite reaction force
If something or someone speeds up, it’s called_____________________
acceleration
