Good question. The amount of 'stuff' in an object is it's mass.
A fundamental distinction we learn in physics is the difference between mass and weight. If we were in deep space, away from any very large objects of mass (like a planet), we would be 'weightless' e.g. not feel the effects of gravity, but we would not be 'massless'. Our mass doesn't change based upon our proximity to large objects (gravitational attraction), but the sense of weight does.
Answer:
distance =13km , displacement=3km
Explanation:
north south does not affect displacement
Answer:
Please find here some hints :
Rule. Newton’s second law, or fundamental principle of dynamics, mentions that a resultant force exerted on an object is always equal to the product of the mass of that object by its acceleration. ... Each force applied to an object causes this object to accelerate in the direction of the force applied.
Is acceleration a force?
The acceleration force, sometimes called the inertia force, is the vehicle’s resistance to speed variations. It holds you back when you increase your speed and pushes you back when you slow down.
