Can displacement be zero even if distance is non zero?
On a three dimensional basis yes it can. Fir instance, if an object is moving directly towards or away from you the angular displacement can be zero though the distance displacement changes.
A -2 displacement towards the north represents a positive displacement towards the south?
Indeed it is.
The total distance an object moves from its starting point is what?
When an object moves, it travels some distance. Distance depends on speed and time traveled.How far you get while traveling is the displacement. Displacement and distance are different.Displacement is the difference from the starting point to the ending point. It is a vector, the vector with direction towards the end point from the starting point and magnitude, the separation.Distance is a scalar, magnitude only, and that is what most people mean by how far they travel.
What is resultant velocity of the plane if a plane travels 100 km per hour to the north with a headwind of 25 km per hour towards the south?
The resultant velocity of a plane is 75 km/hr.
What is resultant velocity of the plane if a plane travels 100 km per hour to the north with a tailwind wind of 25 km per hour towards the north?
The resultant velocity of a plane is 125 km/hr.
If person moves a distance of 3 km towards east then 2 km towards north and then 3.5 km towards east find distance covered by the person?
Total eastward distance covered = 6.5 km Total northward distance covered = 2 km The scalar distance covered by the person and his shoes is 8.5 km. The magnitude of his displacement vector, i.e. the distance of his final location with respect to his initial location, is sqrt[ (6.5)2 + (2)2 ] = sqrt( 42.25 + 4 ) = sqrt( 46.25 ) = 6.8 km (rounded) Note: Technically, that 6.8 km applies only near the equator. For this simple calculation, we handled 'east' and 'north' as if they were orthogonal coordinates on a cartesian plane. The truth is something different on the surface of a sphere, and the farther you get from the equator, the more different the truth becomes. So we know for sure that 6.8 km is not precisely correct. We don't know how incorrect it is, we think it's probably close, and finally, we believe the questioner doesn't care.
What is the origin of centripetal force?
Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.
How simple pendulum obeys simple harmonic motion?
The acceleration of the bob is directly proportional to the displacement and towards the vertical position.If x represents the angular displacement towards the right, from the vertical. and if x', x'' represent the derivatives, then x'' = -kx where k > 0. This is the characteristic differential equation for SHM.
How can you tell on a distance time graph if the object is moving towards or away from you?
Only if you know your location (the coordinate on the distance scale and the time scale) where "you" are can you infer if the object is moving towards you (the absolute distance to the object is decreasing) or away from you (the distance is increasing).
What force allows work to be done?
Any force can produce work if it causes displacement. If displacement is in opposite direction of force, work done will be negative and if displacement is in direction of force work done will be positive. If there is no displacement, work done is zero. Eg: Gravitational force pulls you down towards earth, in pulling you down it does work on you which gets stored in form of potential energy. Energy for A+
How do people put their socks on?
Generally, people take the sock and put it on their feet. They then pull the sock towards the heel, which they then (depending on how long the sock is) pull towards their ankle and then finally towards their knee.
Which system would transmit that impulse towards the brain for interpertation and finally action?
nervous system.
