How long it takes for a ball to roll down a ramp?
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.
When A ball rolls down a slope ramp the acceleration is?
increasing
Does a the mass of a ball affect how fast it rolls down a ramp?
no
Which statement is an obervation if the ramp is steeper then the ball will roll faster or friction slowed the ball down or gravity caused the ball's motion?
"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).
Does the speed of a ball rolling down a ramp change with the kind of surfacce on which the ball is rolling?
yes it does. i just did the experiment.
What is an independent variable in an expirement?
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.
How does the increasing the height of a ramp affect how far a ball rolls down ramp?
how does increasing the height of a ramp affect how far a ball rolls down the ramp
How do you make a ping pong ball go faster down a ramp without altering the outside of the ball and without doing anything to the ramp?
Hmm. . . You can't modify the ball or the ramp. Those are two constraints that don't leave much room for improvement. Is changing the pitch angle of the ramp allowed? I suppose not. How about moving the ramp into a vacuum chamber? If you place the ramp and ball in a vacuum chamber and purge the air, you will eliminate -- or at least greatly reduce -- the friction due to air resistance. In a vacuum, the ball should roll down the ramp faster. How about blowing the ball down the ramp? Get behind the ball and, once it's rolling, blow hard! Better yet, get a hair blow-dryer and really give it a boost.
A student is conducting an experiment to determine how far a ball will roll down a ramp based on the angle of incline. What are three possible controls for this experiment?
The material of the ramp, the volume of the ball, and the mass of the ball.
With how much force does a ramp push a ball rolling down it?
A ramp exerts no force, just gravity.
What are three possible controls when student is conducting a experiment to determine how far a ball will roll down a ramp based on the angle incline?
You can control a lot during this experiment. You can control the weight, size, and density of the ball and the angle of the ramp, to just name a few.

Since gravitiy was the acceleration that caused the ball to roll down the ramp Why wasnt the acceleration of the ball close to 9.8 ms2 2 reasons?
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.
Which ball small medium large will roll down 10 ft the fastest from a ramp?
The small ball
