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
Constant Negative Velocity Observe in which the object below moves along with a constant velocity within the negative direction. The dot diagram displays in which each consecut
Rules to verify how many significant numbers has in a calculated quantity: 1. All nonzero digits are significant. As like 457 cm has three significant values; 0.25 g has two si
What is the force required to accelerate a mass of one kilogram one meter per second per second? Basically, you have defined the Newton. Force is the vector product of mass
snth=u+a/2(2n-1)
For the hydrogen atom, which series describes electron transitions to the N=1 orbit, the lowest energy electron orbit? Is it the: a) Lyman series b) Balmer series
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
