I predict that as the weight increases on the ruler the more it will sag and the more it will sag each time, demonstrated by this rough graph: There should be a strong positive correlation between the sag and the force I predict this because of the rule of compression …

1. Objective 1. To study the effects of the normal reaction and surface area on the force of friction using a block. 2. To estimate and compare the coefficients of static and kinetic friction of different materials. 2. Apparatus * Wooden block (190.0 g) 3 * Elastic strings * Wooden …

“The moment of a (turning) force about a given pivot is defined as follows. Moment of a force = force x perpendicular distance from the pivot to the line of action of the force. The unit of moment is the Newton metre (Nm).”1 Also, “The principle of moments states that …

Aim : To get any object to move in a circle you have to apply a force to it. Methods : With your experiment you don’t mention anything about controlling or measuring the force. All you have measured is the (average) period of the object moving in a circle. From …

The question paper comprises of two sections, A and B. You are to attempt both the sections. i) All questions are compulsory. ii) There is no overall choice. However, internal choice has been provided in all the five questions of five marks category. Only one option in such questions is …

Imagine spinning a ball on a string around you. The ball is traveling in a circular path. But Newton’s first law states that an object in motion stays in motion and that motion is in a straight path, not a circular path. Since the ball is traveling in a circular …
