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 and Air resistance!! x
Yes, it affects the friction.
They should roll at the same rate
It has Potential energy.
The gravitational force is.
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.
The larger the angle of the ramp the farther the ball will roll once it's reached the floor at the bottom of the ramp, until you make the ramp so steep that the ball rolls for shorter and shorter distances each time. Imagine that when the ramp is really steep the ball's direction is mainly into the floor and not along the floor anymore, so it's probably going to bounce a bit depending on what it's made of and not roll very much at all.
"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).
apply friction a rough surface cardboard for example, the rougher it is the slower the ball will roll but to much friction and it will stop altogether.
if the ramp forms a very steep gradient, definately the car will roll for a longer distance. On the contrary, if the gradient formed by the ramp is gentle, then it will roll for a shorter distance
No. Speed and force cause a bowling ball to roll down a lane. Friction may cause a bowling ball to change course on a lane though, and also slow it down.
Yes it rolls faster because the fluid in a can is dense and increases the velocity.
The material of the ramp, the volume of the ball, and the mass of the ball.
The ball rolling down the ramp might not have had time to reach 9.8 m/s^2. Also the coefficient of kinetic friction might have been high for the surface of the ramp.
yes height effects potentail energy because if you have a meter stick and a ramp at 50 centemeters with a block at the bottom then roll a ball down the ramp the block at the bottom will go pretty long but if you put the ramp higher the block will go longer
In other words, does a golf ball roll faster up a hill? No obviously not. It would roll faster down a slope, it's called gravity.
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.
You can make a ramp. In scientific terms, it would be an inclined plain. You can roll balls and drive wheelchairs up and down ramps.
