lesson 5
Doubling the mass will cause the kinetic energy too?
If an object's speed is increased, how would it affect the breakage of an object?
How does air resistance affect a moving object?
If you attach a paper sail to a cart and then use another kart and race them which one will be faster?
the regular one
How would doubling the speed affect the kinetic energy?
It will increase!
If an object's mass is increased, how would it affect the breakage of an object?
If a cart is being launched from a spring to a box, what happens what the cart hits the box.
Energy transfer.
Which one goes faster on 1 hour of gas a motorcycle or a car?
motorcycle
What effect does the mass of an object have on the force involved when it collides with another object?
How much force is applied!
If the speed of an object is increasing at a consistent speed, what will the graphing for this objects kinetic energy look like?
What is another type of friction?
Air resistance.
If you rub two pieces of styrofoam together and rub an eraser with your hands which one will be hotter?
The two pieces of styrofoam
We are doing an experiment on how fast a plant grows with less water materials: 2 pots, dirt, seeds, water, and a light source. What are the controlled variables in this lab?
Type of seed, dirt, and the pots.
If the mass of a moving object is increasing at a consistent rate what will the graphing look like for this objects kinetic energy?
It would be a straight line going up.
When a cart is pushed on a table and begins to slow down, what is causing it to slow down.
Friction with the track/table.
there are 3 types of sandpaper Coarse sandpaper,Medium sandpaper, and Fine sandpaper, which one has the biggest holes?
