... equilibrium- when two or more forces act concurrently (at the same time) on an object, and their vector sum is zero. An object in equilibrium has no acceleration because the forces on it are balanced. According to Newton's 1st law, this means that the object is “not moving” or is moving at constan ...

... A monocycle (bicycle with one wheel) has a wheel that has a diameter of 1 meter. The mass of the wheel is 5 kg (assume all mass is sitting at the outside of the wheel). The friction force from the road is 25 N. If the cycle is accelerating with 0.3 m/s2, what is the force applied on each of the padd ...
