Why is ft (the force due to the friction between the cylinder and the ramp) not included in the equation of motion?
Because the cylinder "rolls without slipping".eurekameh said:Why is ft (the force due to the friction between the cylinder and the ramp) not included in the equation of motion?
Force due to friction is not included in the equation of motion because it is a non-conservative force. This means that the work done by friction is dependent on the path taken and not just the initial and final positions of the object. Therefore, it cannot be expressed as a simple mathematical equation like other conservative forces such as gravity or elastic force.
Yes, friction does affect the motion of an object. It acts in the opposite direction of the object's motion, slowing it down or bringing it to a stop. Friction also causes objects to move in a circular motion when traveling on a curved surface.
Friction is considered a resistance force because it opposes the motion of an object. It acts in the opposite direction of the object's motion, causing it to slow down or come to a stop. This resistance force is caused by the interaction between the surfaces of two objects.
The coefficient of friction is a measure of the frictional force between two surfaces. It affects an object's motion by determining the amount of frictional force acting on the object. A higher coefficient of friction means a greater resistance force, and therefore, the object will experience a slower motion or come to a stop faster.
No, friction is not always a bad thing. While it does oppose motion and can cause wear and tear on surfaces, it also has many important uses. Friction allows us to walk, drive, and grip objects. It is also important in the functioning of machines and tools. Without friction, many everyday tasks would be difficult or impossible to accomplish.
