Lesson 1
What is the energy of motion?
kinetic energy
What are the three collision types? (these are letters)
A, B, and C
Do all objects bend?
Yes.
Force Meaning
The amount of power and energy that is used for movement.
If a rollercoaster is on the top of the track, what energy is it holding?
Potential energy
If an object that has the potential to break hits the ground, what collision type is that?
A
A slow-moving car hit a stationary car.
They change shape when they touch.
True or False: The surface is a controlled variable in a collision.
True
This makes things happen and move.
What is energy?
True or False: speed, color, weight, and mass are all factors of a collision.
False
Did the concrete bend when it was getting close to breaking?
Yes
In a collision, what is the independent variable?
Amount of downward force (newtons).
Formula: 1/2mr^2
What is Kinetic Energy?
In a collision, when both objects collide, what collision type is that?
C
A gold club hits a golf ball.
The golf ball squished.
In the rice noodle experiment, did the rice noodle bend, break, or both?
Break
Formula: mgh
What is Potential Energy?
When there is elasticity in an object, meaning it holds the potential to move, what energy type is that?
potential energy
True or False: When a laser hits something flexible (like a sponge), that gets pushed down, the laser goes down.
True
Generally, in the experiment, which deformed more, the rice noodle or the coffee stirrer?
Coffee Stirrer
