How would you calculate the force pulling the trolley?
With the forcemeter, apply a force to the trolley to accelerate it from rest. Measure the time, t , for the motion over a measured distance, x . Use the formula x = 1/2 at 2 to calculate the acceleration, a. Use F = ma, where m is the measured mass, to find force F in absolute units.
Does weight affect acceleration on an incline?
Why doesn’t the mass of an object affect acceleration down an inclined plane? For the same reason the mass doesn’t affect the acceleration of an object in a free fall, excluding atmospheric drag.
What happens when the friction force equals the pushing force?
As the other answers indicate, if the resisting force due to friction is equal to the force inducing the motion, then the two forces are equal and opposite, and the object will move with constant velocity. A perfect example of this occurs with air resistance.
Which force help the boy to reduce the speed of a trolley?
The boy has to apply a force in the upward direction, to stop it. If you apply a downward force, the trolley will further slide down and will not stop.
What is inclination physics?
The rate at which the object slides down the surface is dependent upon how tilted the surface is; the greater the tilt of the surface, the faster the rate at which the object will slide down it. In physics, a tilted surface is called an inclined plane.
What is the normal force acting on the box?
Explanation: Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force).
How would an object accelerate if the mass is increased or decreased?
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
