Where is acceleration greatest in circular motion?
ac=v2r a c = v 2 r , which is the acceleration of an object in a circle of radius r at a speed v. So, centripetal acceleration is greater at high speeds and in sharp curves (smaller radius), as you have noticed when driving a car.
What will keep the motorbike move in a loop?
Friction counteracts weight to keep the motorcycle moving with constant speed around the loop. The normal force and a component of the weight point toward the center of the loop (the component perpendicular to the loop), so they get to be the centripetal force.
What is apparent weight circular motion?
From my understanding, the apparent weight is the weight that you feel > which is the upward force on you > which is the normal force. …
What is apparent weight formula?
The apparent weight of an accelerating object is the vector sum of its real weight and the negative of all the forces that produce the object’s acceleration a = dv/dt. wapparent = wreal – ma. The apparent weight of a mass m is its real weight minus its mass times the acceleration of the frame (vector addition).
How do you find apparent weight?
In general, an object’s apparent weight is its mass multiplied by the vector difference between the gravitational acceleration and the acceleration of the object. This definition means that apparent weight is a vector that can act in any direction, not just vertically.
What is difference between real and apparent weight?
Your true weight is caused by gravity—it is the force exerted on you by gravity; usually the earth’s gravity. Your apparent weight is the sum of your true weight and a fictitious force associated with your acceleration.
Is normal force apparent weight?
The normal force is equal to your apparent weight. So, you actually feel a little heavier than usual when the elevator accelerates upward, and lighter than usual when the acceleration is down.
What causes apparent weight?
In physics, apparent weight is a property of objects that corresponds to how heavy an object is. The apparent weight of an object will differ from the weight of an object whenever the force of gravity acting on the object is not balanced by an equal but opposite normal force.
Do scales use normal force?
A scale measures the force that the scale is exerting on the object; typically this is a normal force, i.e. one that is normal, or perpendicular, to the surface or the scale. Now, very often, this normal force is equal to the weight, because the object is in equilibrium.
