Question

1. Velocity is known as a vector quantity. What does this tell us about velocity?

a. Velocity will always be positive.
b. Velocity is instantaneous.
c. Velocity will have size and direction.
d. Velocity is the same as acceleration.

Answer 1

c. Velocity will have size and direction.

Answer 2

properly, if the Earth weren't accelerating, there would choose to be a rigidity which counterbalances the solar's gravity, and there is not any longer. whether Earth have been in a uniform orbit, it would choose to be accelerating. we are able to degree our place relative to distant stars to choose that we are nearer to solar in some seasons, and added from the solar in others. We account for this with Kepler's variety of elliptical orbits, shown by calculus and Newton's rules. the two point out, nearer to the solar = extra effective translational kinetic power, much less GPE = swifter tangential velocity.

Answer 3

b,c are true.
when u are saying velocity is same as acceleration did u mean both are vectors,if so then d is also correct.

Answer 4

c. Velocity will have size and direction.

Answer 5

b and c are true

a is false a vector can be positive or negative

d is false acceleration is derivative of velocity

Answer 6

C. Though I feel A also, right?

I mean, how can you have negative size and negative direction?

Answer 7

c is the only answer that is always true, a and b can be true but not always

Answer 8

I think that c is correct

Answer 9

c
