the distance an object moves in a specific amount of time
speed
energy that can be heard
sound
A student is asked to compare sound and light. Which statement should she use?
A. Sound and light are only forms of potential energy.
B. Sound and light are forms of energy.
C. Sound and light are only forms of thermal energy.
B
A hot pot is placed on a cool table. Which way does the heat transfer?
The heat from the pot will transfer to the cool table to warm it up with thermal energy.
When dominoes are set up, they have __________________________________ before someone knocks the first one down.
potential energy or kinetic energy
potential energy
the action of an object bumping into another
collision
a disturbance that travels in a pattern and carries energy
wave
Thermal energy, or heat is related to energy from
A. Movement
B. Stored energy
C. Temperature
C
Which sound has more energy- the squeal of a pig or the croak of a frog? Why does the sound you chose have more energy?
A pig's squeal has more energy because it has a high pitch. High pitch has faster vibrating particles.
