Mastering the Basics of Motion

Distance travelled is the total length covered by a body during its motion, while displacement is the shortest distance between the initial and final positions of the body. For instance, a person walking 10 meters forward and then 10 meters backward will have a distance travelled of 20 meters but a displacement of 0 meters.

Speed is a scalar quantity that measures how fast an object is moving. Velocity is a vector quantity that measures both the speed and direction of an object's motion.

Distance travelled is the total length of the path covered by a moving body, regardless of the direction. Displacement is the distance between the initial and final positions of the body, measured in a straight line. For example, if a person walks 10 meters east and then 10 meters west, the distance travelled is 20 meters, but the displacement is 0 meters.

<p>Uniformly accelerated motion is a type of motion where the acceleration of a body is constant. The three equations of motion for uniformly accelerated motion are: v = u + at, s = ut + (1/2)at^2, and v^2 = u^2 + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration, t is the time taken, and s is the distance covered.</p> Signup and view all the answers

<p>Uniformly accelerated motion is a type of motion in which the velocity of a body changes by the same amount in each unit of time. The three equations of motion for uniformly accelerated motion are:</p> Signup and view all the answers

<p>Circular motion is the movement of an object along a circular path. An example of uniform circular motion is a satellite orbiting the Earth at a constant speed and altitude.</p> Signup and view all the answers

<p>Circular motion is the movement of a body along a circular path, whereas linear motion is the movement of a body along a straight path. In circular motion, the direction of the velocity vector changes continuously, even if the magnitude of the velocity remains constant. An example of uniform circular motion is a satellite orbiting the Earth or an athlete running on a circular track at a constant speed.</p> Signup and view all the answers

<p>Circular motion is the motion of a body along a circular path, while linear motion is the motion of a body along a straight path. An example of an object in circular motion is a satellite orbiting the Earth. It is considered uniform circular motion because its velocity and direction are constant, and its acceleration is directed towards the center of the circle.</p> Signup and view all the answers
