The difference between speed and velocity is that velocity includes
a. direction.
c. time.
b. distance.
d. weight.

a. direction.

Explanation:

Velocity is a vector, so it includes both a) a magnitude and b) a direction.

The magnitude of the velocity is the speed, which is the ratio between the distance covered and the time taken:

However, speed gives only information on how fast is the object traveling. Instead, velocity gives also information on the direction of the motion of the object.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
