☆☆☆☆☆newton second law of motion
Newtons first law of motion states that an object in motion will stay in motion and an object at rest will say at rest.
fluid friction.
One third its weight on earth's surface
The dnsity of a submerged submarine is the same as the density of the water if the density of the submarine was grater it will sink, if the density was less it would float.
the difference is 10
because 60
+ 70
130
- 120
10= friction
The magnitude of the balls displacement is 9 meters.
A projectile has an initial forward velocity.
reaction
An unbalanced force can completely destroy the object (depending upon its mass and power of force) or can gradually move it or it can also have no effect on the object.
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
It produces hydroxide ions - Jon
It has variable acceleration
For every action there is an equal and opposite reaction.
Isaac Newton defines force as mass times acceleration.
There is little mass to the bug compared to an automobile.
the earth and moon have different values for the acceleration due to gravity.
[H3O+] = 1x10^-7 M = hydronium ion concentration
[OH-] = 1x10^-7 M = hydroxide ion concnetration
Water is neither an acid nor a base, and water does not "react" with a base. It may dissolve it.
