a. add
b. subtract
A. ADD
Kinetic energy is the energy of ___________ while potential energy depends on M_________ and H__________.
movement, mass, height
Energy transformation is when one energy transforms into another. Give an example of kinetic energy turning to potential energy.
What are the 2 types of waves?
A. longitudinal and latitudinal
b. longitudinal and transverse
B- longitudinal and transverse
There are three items in a density tower. Water is in the middle, honey is at the bottom and oil is on top. Which of the 3 items is the MOST dense.
Honey, because the denser a substance the lower it sinks
When finding the net force of two objects going OPPOSITE directions you
a. add
b. subtract
B. SUBTRACT
Two balls are suspended in the air at equal heights. One ball is 5kg while the other is 7kg. Which ball has greater potential energy.
The ball with more mass has more potential energy.
Give an example of electrical energy turning into mechanical energy.
plugging in a fan, electric cars, washing machines
Which wave travels parallel or side to side.
Longitudinal
City, girls, really, love, their phones is a saying that helps us remember the signs of a chemical reaction. You have 1 and a half minutes to name what each letter represents.
c- color change (unexpected), g- gas/odor, r-rust/tarnish, l- light, t-temperature change (unexpected), p- precipitate (2 liquids forming a solid)
Tom, Billy and Lucy were playing tug of war. Tom and Billy pulled LEFT at 6N while Lucy pulled RIGHT at 7N. What was there net force AND was it balanced or unbalanced.
Net force was 1N RIGHT and it was unbalanced.
When a rollercoaster reaches its peak is it at its greatest potential energy or greatest kinetic energy?
Potential NRG
Give an example of chemical potential energy to any kinetic energy.
batteries making our phones work, gas powering our cars, rocket launching, human movement (powered by the food we chemically break down)
Which wave travels perpendicular or up and down.
Transverse
The "staircase" on the periodic table holds
a. metals
b. non metals
c. metalloids
C. Metalloids
Normal force is like sitting in a chair or standing up, it runs perpendicular. Which would be an example of an APPLIED force?
a. laying down sleeping
b. push a cart
b. pushing a shopping cart because applied forces are forces that have CONTACT with another object.
An apple fell from a tree. Explain where the potential energy is and where the kinetic energy is.
The the apple is on the tree high up it has potential energy, when it falls it turns into kinetic energy.
What energy transformation is playing a guitar?
Mechanical to Sound
Wave travel through
A. Medians
B. Mediums
B. Mediums
When combining red and yellow paint a student observed that it turned orange. Was this a chemical reaction yes or no AND explain why.
No because the color change was expected not unexpected.
Newtons third laws states that for every action there is an equal and opposite reaction. For example, hitting a baseball with a bat, the ball hit the bat AND the bat pushes back on the ball. Give 2 more examples of action reaction.
pushing a door shut, sitting in a chair, typing, pretty much anything that has a reaction to your action
CAGE MELTS. Give the names of at least 5 of the types of energy each letter represents.
Chemical- PE, Atomic/nuclear- PE Gravitational- PE, Elastic- PE
Mechanical-KE, Electrical-KE, Light-KE, Thermal-KE, Sound-KE
What energy transformation is lighting a fire?
Chemical to thermal and light
True or False waves can only travel through the air
FALSE, waves can travels through solids liquids and gasses
