Measure if how far an object has moved.

You can't really measure how far an object has moved. If you weren't
watching it the whole time, you can only measure how far it <em>IS</em> now from
where it started, but you don't know what route it traveled to get there.

The distance between where it started and where it ended up is called
the object's "displacement".  That's the length of the straight line between
those two points.  And it's also the shortest possible distance the object
could have moved in order to get to where it is now.

Funny thing:  When you walk all the way around a yard, a track, or a building,
or drive a car one lap around the track, your <em>displacement</em> is zero, because
you end up in the same place you started from, and the distance is zero.
If somebody saw you before and after, but didn't see you walk or drive,
they wouldn't know that you had moved at all.

Answer:

Energy is essentially work done by an object or on object.

From,

W = Fd

It's directly proportional to mass.

from,

K. E = 1/2mv²

Energy is directly proportional to mass.

P. E = mgh

Energy is directly proportional to mass.

H = mc∆T

Energy is directly proportional to mass.

Thus increasing mass will increase the energy also imparted on another object since all the above eqns show that relationship.

And for 2 moving bodies

K.Ei = K.Ef(energy conservation)

m1u²1 + m2u²2 = m1v²1 + m2v²2

The relationship is the same that the greater mass the greater the impact.

the base of a rectangular vessel measure 10m by 18cm. water is poured into a depth of 4cm. (a) what is the pressure on the base?
Alex787 [66]

Answer:

a) P =392.4[Pa]; b) F = 706.32[N]

Explanation:

With the input data of the problem we can calculate the area of the tank base

L = length = 10[m]

W = width = 18[cm] = 0.18[m]

A = W * L = 0.18*10

A = 1.8[m^2]

a)

Pressure can be calculated by knowing the density of the water and the height of the water column within the tank which is equal to h:

P = density * g *h

where:

density = 1000[kg/m^3]

g = gravity = 9.81[m/s^2]

h = heigth = 4[cm] = 0.04[m]

P = 1000*9.81*0.04

P = 392.4[Pa]

The force can be easily calculated knowing the relationship between pressure and force:

P = F/A

F = P*A

F = 392.4*1.8

F = 706.32[N]
