Question

Collect all the points regarding all the formulae, displacement,speed, velocity and acceleration

Answer 1

Answer:

$u=\frac{d}{t}$

$v=\frac{s}{t}$

$a=\frac{v}{t}$

where u is speed, d is distance, v is velocity, a is acceleration, t is time.

Explanation:

• Displacement of a body is defined as the minimum distance or the shortest distance a body travels. It is generally denoted by "s"
• Example: Suppose you travel on a square track and you want to reach the opposite corner of the square, you have two choices either you will travel the two sides or directly you can go by the diagonal. the diagonal is the shortest distance and it will be your displacement.

• Speed of the body is defined as the ratio of distance travelled by the body to the time taken by the body to cover that distance. $u=\frac{d}{t}$ where d is the distance(m) and t is time(t) and u is the speed.
• Velocity of the body is defined as the ratio of displacement to the time taken. $v=\frac{s}{t}$

• Acceleration of a body is defined as the ratio of velocity to time. $a=\frac{v}{t}$
