Lesson 5: Peak Force Cart Lab
"When an object collides with another object, how does changing the object's speed affect the force of impact?" What are the independent, dependent, and controlled variables in this lab?
Independent variable- Speed
Dependent Variable- Amount of force
Controlled Variable - Spring scale
How much does doubling the speed or doubling the mass affect the kinetic energy of an object and the damage it causes?
If we double the speed the kinetic energy would increase expodtionally.
Where did the energy in our launcher system come from, and after the Collisions where did it go?
The Spring scale started channeling the energy and transferred to the cart when it got pushed, which pushed it out to the environment.
How do other contact forces from interactions ( with the air and the track) cause energy transfers in the launcher system?
The 2 contact forces ( Friction and Air resistance ) stopped the cart with the friction which is created to thermal energy.
"When an object collides with another object, how does changing the object's mass affect the force of impact?" What are the independent, dependent, and controlled variables in this scenario?
Independent variable- Mass
Dependent Variable- Force
Controlled Variable- The ruler
How much does doubling the mass of an object affect the kinetic energy and damage it causes?
If we double the mass, the kinetic energy would double.
When the cart slows down in this lab ( hint:look at time 4) why did it slow down and it didn't continue pushing the box?
Friction and Air Resistance stopped the cart.
Why didn't the cart without the sail go all the way to the tape like the cart with the sail?
The cart without a sail demonstrated air resistance and friction against the cart and stopped the cart.
How does changing the mass or speed of an object affect the forces on the objects during collisions?
changing the mass or speed of an object affects the forces on the object during collisions.
How much does doubling the speed or doubling the mass affect the kinetic energy of an object and the resulting damage that it can do in a Collisions?
Doubling the speed would increase the kinetic energy because it's moving so that would be considered as KE.
Doubling the mass will also cause kinetic energy to decrease because the mass would weigh down the cart to the point that it stops moving.
When the cart is getting pushed off the launcher is there a energy transfer and a contact force?
Yes,there is an energy transfer and contact force.
When the Eraser and the table got rubbed together was it rough or smooth?
Smooth.
