What You Will Learnt?

✅ Motion is a change of position; it can be described in terms of the distance moved or the displacement. 

✅ The motion of an object could be uniform or non-uniform depending on whether its velocity is constant or changing. 

✅ The speed of an object is the distance covered per unit time, and velocity is the displacement per unit time. 

✅ The acceleration of an object is the change in velocity per unit time. 

✅ Uniform and non-uniform motions of objects can be shown through graphs. 

✅ The motion of an object moving at uniform acceleration can be described with the help of the following equations, namely

v = u + at
s = ut + ½ at²
2as = v ² – u ²

where u is initial velocity of the object, which moves with uniform acceleration a for time t, v is its final velocity and s is the distance it travelled in time t. 

✅ If an object moves in a circular path with uniform speed, its motion is called uniform circular motion.
