acceleration down a ramp with friction
With no friction, the box will accelerate down the ramp. Align the coordinate system with the acceleration. +x = down the ramp and +y = perpendicular to the ramp. The forces need to be split into components.The normal force is OK-it's in the +y direction.Split the force of gravity into a component down the ramp, and a component perpendicular to the ramp.he ramp is 3.0 m long. If we knew the acceleration of the box we could use the constant acceleration equations to find the time. By analyzing the forces on the box the acceleration can be determined. Once again, the key is to construct a good free-body diagram. OBJECTIVE: To study the motion of an object traveling up and down a ramp in the absence of friction and drag forces. To measure the acceleration of such an object and see how the acceleration depends on the ramp angle.THEORY: If an object falls straight down and air resistance is small, we found in the last experiment that it accelerates down at 9.8 m/s2.an you think of different ways that the acceleration, a, might depend on the angle, Remember that we do expect. a = 0 m/s2 at 0o and a = 9.8 m/s2 at 90o. a(() = ???

Without friction, this force would cause the object to accelerate down the incline. If friction was present but less than this parallel force, then there would still be an acceleration down the incline, but it would be less of an acceleration than you would see on a frictionless inclined plane.n the above picture you might imagine that the object could slide down the incline. If there is only a small amount of friction between the object and the wooden surface, this could certainly be the case. The frictionless inclined plane: Here, at first, we will consider inclined planes with no friction. This means that the net force equals the component of the weight parallel to the ramp, and Newton's 2 nd Law says: This means that any object, regardless of size or mass, will slide down a frictionless ramp with the same acceleration (a fraction of g that depends on the angle of the ramp).liding Down an Incline: Next, let's consider letting objects slide down a frictionless ramp. Now, there are 2 forces on the object-its weight pulls down (toward the center of the Earth) and the ramp pushes upward, perpendicular to the surface of the ramp (the normal force). Application of Newton's second law to mass on incline with pulley. Given an incline with angle degrees which has a mass of kg placed upon it. It is attached by a rope over a pulley to a mass of kg which hangs vertically. The friction between the mass and the incline is represented by a friction coefficient mu= .Taking downward as the positive direction for the hanging mass, the acceleration will be Acceleration = m/s². With this acceleration, the tension in the rope will be.pplication of Newton's second law to mass on incline with pulley. Given an incline with angle degrees which has a mass of kg placed upon it.

We can draw a basic free body diagram for this situation, with the force of gravity pulling the box straight down, the normal force perpendicular out of the ramp, and friction opposing motion (in this case pointing up the ramp).e can draw a basic free body diagram for this situation, with the force of gravity pulling the box straight down, the normal force perpendicular out of the ramp, and friction opposing motion (in this case pointing up the ramp).

They then wind the car up so that it can accelerate up the ramp for at least a short distance. They should draw a free body diagram showing the forces on the car as it climbs the slope.

Kinetic friction is involved any time an object is moving up or down a ramp.. You can solve problems with kinetic friction as easily as those that involve static friction.f she has a mass of 30.0 kg and the coefficient of kinetic friction is 0.10, how much force will you need to apply to keep her going? You’re pushing a box of books with a mass of 25 kg up a 40-degree ramp.
