Gravity pulls down, normal force pushes up. The normal force is less than the gravitational force because the hill is curving downward away from the bike, and the bike is accelerating downward. Downward is toward the center of the circle, at the moment the bike is atop the hill. cf冒险模式怎么玩

WebIn most scenarios you see in physics' problems, a string is the provider of the centripetal force; it acts as the tether to the object making it go in a circle rather than flying off … WebThat means The mass is in uniform circular motion and the path of its motion is vertical circle. How does the tension change with respect to the position of the mass. More specifically is the tension in the string is only due to circular motion ($mv^2/R$) or gravity plays a part in it ($mv^2/R$ + something due to weight)? homework-and-exercises
