lesson 1
name some examples of kinetic energy?
people, pencils, cheetas, cars, and sharks.
Do items always change shape when pressure is applied to them?
Yes, if it's a little bit, they change shapes.
What is an independent variable?
The cause/ the variable that changes every time you test.
What is it called when two objects apply force to each other and possibly damage one another?
collisions.
What are class norms?
Rules to abide by in the science room.
Name some examples of potential energy?
the top of the roller coaster before it goes down, a ball at the top of a hill.
free points
yay
What is a dependent variable?
The effect of an independent variable.
What is stored energy called?
Potential energy (PE).
how many types of collisions are there?
3
What happens when two things hit each other?
They collide, cause damage to each other, or cause a change in shape.
Does the shape of objects change after or during a collision?
depends on the amount of force; if it is less force, it will be a temporary change, and if it is more force, then it could result in a permanent change.
Which item has a higher elastic limit, a coffee stirrer or a rice noodle?
coffee stirrer.
What is the energy of movement called?
kinetic energy (KE).
How many types of KE are there?
5
What are the factors in a collision
height, speed, surface, material, width, amount of force, and mass.
What causes changes in the motion and shape of colliding objects?
The forces between two objects energy transfer.
How much pressure do you have to put on an item for it to make a permanent change?
push it past its elastic limit.
What is it called when an object bends, distorts, or changes shape?
Deformation
how many units are in a MP?
idk...
What is a type A collision? Type B? Type C?
Type A is the damaged item moving at first and the other object motionless. Type B is the damaged item motionless and the other object moving. Type C is both objects moving.
When two items collide, is the bigger object more likely to do more or less damage?
more.
How much pressure do you have to put on an item for it to make a temporary
Don't push it past its elastic limit and keep it inside that amount of force.
What is it called to use the maximum amount of pressure on an object until it permanently deforms?
elastic limit.
where are the science notebooks located?
counter or B2 cabinet.
