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?
The force of gravity must be greater than the force of friction between the ramp and the car's wheels. This allows the car to overcome the resistance and move down the ramp.
What is main force tht causes a to to roll down a ramp?
The main force that causes an object to roll down a ramp is gravity. Gravity is pulling the object downward, which causes it to accelerate and roll down the incline. Friction between the object and the ramp also plays a role in causing the object to roll.
What force causes a ball to roll down a ramp?
The force of gravity causes the ball to roll down the ramp. The force of gravity pulls the ball downward towards the center of the Earth, causing it to accelerate as it rolls down the ramp.
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
How long it takes for a ball to roll down a ramp?
The time it takes for a ball to roll down a ramp will depend on the angle of the ramp, the friction between the ball and the ramp, and the initial velocity of the ball. However, in ideal conditions with no friction and starting from rest, the time can be calculated using physics equations for motion.
Does a full can roll faster than a empty can down a ramp?
Yes, a full can will typically roll faster than an empty can down a ramp due to the increased mass providing more momentum. This allows the full can to overcome friction and other resistive forces more easily, leading to a faster roll.
How do you make a can roll slowly down a ramp?
To make a can roll slowly down a ramp, you can adjust the angle of the ramp to make it less steep, which will reduce the speed at which the can rolls. Additionally, you can create friction between the can and the surface of the ramp by adding a material like sandpaper to slow down the can's movement. You can also place obstacles on the ramp to create resistance and slow down the can's progress.
What are two forces that could cause a ball to roll down hill?
Two forces that could cause a ball to roll downhill are gravity, which pulls the ball downward, and friction, which helps to reduce motion resistance and allows the ball to roll smoothly.
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 type of ball will roll the farthest down the ramp?
A ball with less friction, such as a smooth, hard ball like a metal ball or a marble, will typically roll the farthest down a ramp compared to a ball with more friction, such as a rubber ball or a soft foam ball.
