Which ball small medium large will roll down 10 ft the fastest from a ramp?
The small ball
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.
Why does a ball roll faster down a steep ramp than down a shallow ramp?
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.
How do you do a log roll?
lie down on you chest and turn to the oppersite side and carry on traveling !
What is the point in having your 5 a day?
cause your ard, roll at me bro.
What must be true about the forces in order for a car to roll down a ramp?
gravity
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.
Why would a crayon roll down a ramp but need force to move up a ramp?
The heavy the crayon, it will roll down but it needs force to move it back up
What is main force tht causes a to to roll down a ramp?
Gravity
What are two forces that could cause a ball to roll down hill?
Gravity and Air resistance!! x
Does the texture of a ramp matter when you roll a car down?
Yes, it affects the friction.
Which is the main force that causes a toy car to roll down a ramp?
The gravitational force is.
What type of energy does a cart have before it starts to roll down a ramp?
It has Potential energy.
What forces caused to roll down the incline?
The Earth's gravity will force a round object to roll down an incline (slope).
Which ball small medium large will roll down 10 ft the fastest from a ramp?
The small ball
Example of a inclined plain?
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.
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).
