What is Motion When a body does not change its position with time, we can say that the body is at rest, while if a body changes its position with time, it is said to be in motion.Analysing Linear MotionLinear motion is motion in a straight line. Non-linear motion is motion that is not in a straight line. When analysing linear and non-linear motion, … [Read more...] about What is Motion and Types of Motion

What Is Circular Motion
Circular Motion When a body moves in such a way that its distance from a fixed point always remains constant, then its motion is said to be the circular motion.Uniform circular motion: If the radius vector sweeps out equal angles in equal times, then its motion is said to be uniform circular motion.In uniform circular motion speed remains constant. Linear velocity, … [Read more...] about What Is Circular Motion
What Are The Equations Of Motion
Equations Of Motion Motion under uniform acceleration1st Equation of motion For an object moving with uniform velocity, v, its displacement, s after time, t is given by: s = v × t Consider a body having initial velocity 'u'. Suppose it is subjected to a uniform acceleration 'a' so that after time 't' its final velocity becomes 'v'. Now we know,or v = u + at … [Read more...] about What Are The Equations Of Motion
How to Find Acceleration Using a Velocity Time Graph
What Is Acceleration Rate of change of velocity is called acceleration. It is a vector quantitywhere u is the initial velocity of the object, v is its final velocity and t is the time taken. Unit of acceleration = m/s2 or ms-2 If the velocity of a body decreases, then it will experience a negative acceleration which is called deceleration or … [Read more...] about How to Find Acceleration Using a Velocity Time Graph
What Is The Difference Between Distance And Displacement
What Is Distance And Displacement In Physics The path length between the initial and final positions of the particle gives the distance covered by the particle.Distance is defined as the total length of the path travelled from one location to another. The distance travelled by the car is given by the following, Distance travelled = (200 + 500 + 600 + 300) … [Read more...] about What Is The Difference Between Distance And Displacement
