Answer:
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.
Explanation:
v= u + at
s =( u + v ) t /2
s = ut + at2/2
v2 = u2 + 2as
Units and Numbers
In order to determine an object’s speed on a Speed vs. Time graph, the axes MUST be labeled with United and numbers.
Acceleration I’m pretty sure
Gravitational pull
