Question

Which graph best represents the relationship between KE and mass?

Answer 1

Answer:

its the fist graph, because it relates to kinetic energy & mass. the others are wrong becasue it is not an answr choice

Explanation:

Answer 2

Answer:

First graph

Explanation:

Here we need to tell which graph best represents the relationship between kinetic energy and mass . As we know that ,

$\sf\red{\longrightarrow}$ KE = 1/2 mv²

Here we will plot KE on y axis and mass of x axis. And it is in form of y = mx + c .On comparing the given equation with ,

$\sf\red{\longrightarrow}$ y = mx + c

• c = 0
• m = 1/2v²

Therefore the line will be straight and will pass through origin with a slope v²/2 .

From the attached graphs , first graph is correct .

First graph best represents the relationship between kinetic energy and mass.
