DIt acts down
Always toward the center of the Earth.
A size but no direction. Mass is a scalar but the force we call weight is a vector: it always points down.
upward direction
And it not only DOES; it works in no other way. Friction is a sneaky thing. You know how a thermos "knows" to keep the hot stuff hot and the cold stuff cold? Well, friction always knows in which direction you're trying to go and pushes against you!
DIt acts down
No, they can NEVER act in the same directions.
Always toward the center of the Earth.
Frictional force must always act in opposite directions
No buoyant force would act only in the upward direction against the weight of the body as it gets immersed in the liquid.
N o! the upthrust can not act at a distance because it acts on the centre of gravity of the object submerged in water in the opposite direction of weight.
A vector always consists of a direction and magnitude. For example, a vector representing the weight of an object that is 35N would be represented as an arrow pointing downward with a magnitude of 35N. You could also represent the weight of 35N as -35N, in which the negative symbol indicates a downward force.
it acts in the opposite direction of motion or force
Because the weight of ship balances the upthrust force , We know that weight always act downward and upthrust force always act upward so we can say that it comes in equillibrium condition . that's why it keeps floating on water..........
Friction always acts in the opposite direction to that of the motion of the other object. Meaning, friction slows down the motion of an object by exerting opposing forces on it.
A size but no direction. Mass is a scalar but the force we call weight is a vector: it always points down.
Objects in motion continuously change position.To change direction, a force needs to act upon them.
