gravity assuming the car was off, and not in park
The small ball
The independent variable in an experiment is the variable that the experimenter varies or changes. For instance, if I'm studying the effect of the steepness of a ramp with the time it takes a ball to roll down the ramp, I change the steepness of the ramp (the independent variable) and measure the time (the dependent variable). Hope this helps.
Potential Energy of the ball on the shallow ramp and the ball on the steep ramps are different: PE = mass x gravity x height. This potential energy is converted to Kinetic energy or motion energy. KE = 1/2mv^2. If there is more potential energy to convert to Kinetic energy then it will result in increased speed.
lie down on you chest and turn to the oppersite side and carry on traveling !
cause your ard, roll at me bro.
gravity
Twice as long as it takes to roll halfway down the same ramp. Without knowing the size of the ball, and the length & angle of the ramp, thats the best I can tell you.
The heavy the crayon, it will roll down but it needs force to move it back up
Gravity
Gravity and Air resistance!! x
Yes, it affects the friction.
The gravitational force is.
It has Potential energy.
The Earth's gravity will force a round object to roll down an incline (slope).
The small ball
A ramp. Items you can not lift up, you can roll up a ramp. People can not lift someone in a wheel chair, but they can roll him up a ramp or an inclined plain.
"If the ramp is steeper than the ball will roll faster" can be observed during experiments. "Friction slowed the ball down" and "Gravity caused the ball's motion" are both conjectures (guesses).
