Basic principles of kinematics

The students were asked to calculate the maximum height reached by the ball, when it was thrown upwards at a speed of 6 meters per second. Similarly, a morning walker moves on a semicircular track with a radius of 35 meters. If it starts at one end of the track and goes to the other end, they were asked to calculate the distance traveled and also the displacement.

The analysis of the motion of bodies is widely studied in a branch of physics known as mechanics.

Kinematics deals with the trajectory of moving bodies. The cause of its motion is not studied in kinematics. The movement of a vehicle on a straight road is an example of movement in one dimension. The motion of a projectile on the Earth’s surface is an example of motion with uniform acceleration in two dimensions. A cricket ball thrown by a fielder is an example of a projectile.

A particle or an object is said to be in motion if it occupies different positions at different instants of time. Otherwise, it is said to be at rest.

A change of position in a particular direction is known as displacement. Distance is defined as the total path traveled by an object in any direction. Displacement, on the other hand, is the shortest distance in a particular direction.

If a vehicle travels a distance of 150 kilometers in three hours, its speed is 50 kilometers per hour. The speed of a vehicle is its speed in any specified direction. The speed (v) is given by the formula, displacement (s) / time
