Answer the following questions:
1) Describe vectors and scalars? A vector represents the direction and position.
A scalar represents speed and distance. Vectors has both direction and
magnitude while scalars only have magnitude. The vector is the velocity
Determining vector and scalar behavior of velocity and acceleration
It is possible to determine the behavior of vectors and scalars using velocity and
acceleration. In this case vector represents velocity and scalar represents acceler
(a) What force does the floor exert on the block?
Direction: Straight up
The block is not moving therefore the weight of the block is downward and the floor exerts
the force upwards.
(b) If a rope is tied to the block and run vertically
