Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter.
Distance: The actual length of path traversed by a body in a sub interval of time is known as distance. It is the actual path travelled by an object between its final and initial positions. It is a scalar function and its unit in SI is meter. Displacement can be positive, zero or negative but distance is always positive. If a particle goes in a straight line without modification in its direction, the value of displacement is same to the distance travelled. Otherwise it is usually less than it. Thus, Displacement distance
On the planet Newtonia, a simple pendulum having a bob with mass 1.25 kg and a length of 185.0 cm takes 1.42 seconds, when released from rest, to swing through an angle of 12.5 deg

When a moving body changes with time,then we say that the body has acceleration.simentaniously the change in velocity is equal then it is called uniform acceleration .
what are unlike parallel forces with example?
It states that angular momentum of a system remains conserved if no net torque is acting on the system.
