position

force

speed

velocity


Question 2. 2. Which of the following describes acceleration? (Points : 1)
s/m

m/s

m/s2

m2


Question 3. 3. Which of the following is the main difference between speed and velocity? (Points : 1)
Speed has direction and velocity.

Velocity has both speed and direction.

Speed is constant.

Answer 1

1.d 2.? 3.?

Answer 2

2 is c and 3 is a

Answer 3

Thank you so much :)

Answer 4

Acceleration is change in velocity

Unit of acceleration is \(\sf m/s^2\)

Speed is a scalar quantity i.e has only magnitude but velocity is a vector quantity and has both magnitude and direction.

Answer 5

@Abhisar so are you saying 3 is a?

Answer 6

3 is c

Answer 7

Velocity is speed + Direction

Answer 8

oh thanks :)
