A classic physics textbook version of this problem asks what will happen if you roll two cylinders of the same mass and diameter—one solid and one hollow—down a ramp. The answer is that the solid one will reach the bottom first.

How do you do ramp problems in physics?
Do heavier objects roll down a ramp faster?
After a two sample t-test, we find that heavier rolling objects have a statistically faster clear time for a given inclined plane in comparison to lighter rolling objects. In addition, heavier objects will be more resistant to the effects of air resistance and rolling resistance.
Does it take longer for a block to go up or down a ramp?
Going up: friction and gravity work together; the block decelerates quickly. Going down: friction and gravity work in the opposite direction; the block accelerates slowly. Sliding up takes less time.
Which goes faster down the ramp the disk or hoop?
It is shown that the one that reaches the bottom first depends not on the mass or radius, but on the shape. To illustrate this further, a wooden disk, clad with a metal ring, rolls down faster than the hoop but slower than the wooden disk.
Which objects roll down an incline with the greatest acceleration?
Which objects roll down an incline with the greatest acceleration? Any solid cylinder will roll down an incline with greater acceleration than any hollow cylinder if the… When a gymnast moves from an extended position to a tucked position, she…
How do you solve a ramp question?
What is the formula for inclined plane?
Inclined plane formulas for a cubic block Gravitational force: F g = m × g F_g = m times g Fg=m×g, where m is the mass of object and g is the gravitational constant. It can be divided into two components: F i = F g × sin θ F_i = F_g times sintheta Fi=Fg×sinθ – parallel to inclined plane; and.
How do you resolve forces on an inclined plane?
In the case of inclined planes, we resolve the weight vector (Fgrav) into two components. The force of gravity will be resolved into two components of force – one directed parallel to the inclined surface and the other directed perpendicular to the inclined surface.
Does weight affect how fast an object rolls down a ramp?
Weight affects speed down the ramp (the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
Does a heavier object go down a hill faster?
Many people expect that a heavier wheel will naturally roll downhill faster than a lighter one. But when an object rolls downhill, its speed depends not on the weight of the wheel, but on where the weight is located. When weight is located far from the center of the wheel, the wheel is harder to get rolling.
Why do things roll faster down a steeper slope?
The change in speed on slopes is due to gravity. When going downhill, objects will accelerate (go faster), and when going uphill they will decelerate (slow down). On a flat surface, assuming that there is little friction, they will then maintain a constant speed.
What affects acceleration on a ramp?
Acceleration on a ramp equals the ratio of the height to the length of the ramp, multiplied by gravitational acceleration. Acceleration on a ramp equals the sine of the ramp angle multiplied by gravitational acceleration.
How does the angle of ramp affect acceleration?
As the angle increases, the component of force parallel to the incline increases and the component of force perpendicular to the incline decreases. It is the parallel component of the weight vector that causes the acceleration. Thus, accelerations are greater at greater angles of incline.
Is it easier or more difficult to lift the object up than to roll it up the ramp?
Is it easier or more difficult to lift the object than to roll it up the ramp? It requires less force over a longer distance to roll the object up the ramp, but some kids might say that it’s easier to lift the object.
Which one gets to the bottom of the ramp first and why construct the correct explanation?
One is solid; the other is hollow. If you place them on a ramp, the gravitational torques that make them roll down the slope are the same. But one sphere has a greater angular acceleration, so it reaches the bottom of the ramp first.
Why does a disk roll faster than a ring?
Why does a solid disc roll down an inclined plane faster than a ring? The solid disc beats the ring because it has a lower “resistance” to motion. All mass has the property of resisting a change in motion, or inertia. An object in motion wants to stay in motion, and an object at rest wants to stay at rest.
Which will roll down an incline faster a can of water or a can of ice?
Answer and Explanation: The can of water will roll down faster than the can of ice. Because, the can of ice is rigid, that will generate a particular rotational kinetic energy so it makes the linear speed or linear kinetic energy of the can of ice comparatively lower than the can that contains water.
Does mass affect acceleration down a ramp?
The object rotates about its point of contact with the ramp, so the length of the lever arm equals the radius of the object. This result says that the linear acceleration of the object down the ramp does not depend on the object’s radius or mass, but it does depend on how the mass is distributed.
Which rolls to the bottom of a hill sooner a car tire alone or the same tire mounted on a rim?
Which rolls to the bottom of a hill sooner, a car tire alone or the same tire mounted on a rim? the mounted tire, regardless of its weight.
Which ball will roll faster?
There are cases where a larger ball can travel faster than a smaller ball. However, consider the case where both balls are under the same conditions (same mass, and placed at the same height on the same inclined plane, and assume negligible air resistance), then the smaller ball will travel faster than the larger ball.
How do you calculate the work done by a slope?
How do you solve an inclined plane without friction?
How do you find the velocity of an object sliding down a ramp?
When an object is shot from the bottom of a long smooth inclined?
When an object is shot from the bottom of a long smooth inclined plane kept at an angle 60° with horizontal, it can travel a distance x1 along the plane. But when the inclination is decreased to 30° and the same object is shot with the same velocity, it can travel x2 distance.
