Galileo Galilei(1564 – 1642) Galileo Galilei was born on 15 February 1564 in Pisa, Italy. Galileo, right from his childhood, had interest in mathematics and natural philosophy.But his father Vincenzo Galilei wanted him to become a medical doctor. Accordingly, Galileo enrolled himself for a medical degree at the University of Pisa in 1581 which he …
“A body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.“ According to Newton’s first law of motion, a body won’t begin to move unless and until an outside force acts on it. When something starts moving, it won’t stop or change …
Solution: Mass of Hammer, m = 1 kgInitial Velocity, u = 6 m/sFinal Velocity, v = 0 m/sTime Taken, t = 0.1 sThe acceleration is: a = (v – u )/t a = ( 0 m/s – 6 m/s ) / 0.1 sec Therefore, a = – 60 m/s2 [-ve sign means retardation]Thus, the retarding …
Solution: m (Mass of toy car) = 2 Kg,a (Acceleration) = 8m/s2,F is Force to be applied by Anshal = m × a = 2 Kg × 8 m/s2 = 16 Kgm/s2 = 16 N.
Solution: Given, Acceleration (a) = 4.00 m/s2MAss (m) = 1000 kgTherefore, F = ma = 1000 × 4 = 4000 N
The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the …
What is Uniform Circular Motion? The movement of a body following a circular path is called a circular motion. Uniform Circular Motion is the term used to describe a body moving in a circular path at a constant speed. While the velocity in this case changes, the speed is constant.A particle must be experiencing some …
