Consider this expression below:
A body X exerts a force FX on another body Y. In return, body Y exert a force FY back on body X. The forces FX and FY are equal in magnitude but opposite in direction.
Putting the above expression into equation:
FX = -FY
Where FX is the action force
FY is the reaction Force
The above expression relates to _____.
ANSWER: Newton's 3rd Law of Motion
Newton's 3rd law of motion states that:
To every action, there is an equal and opposite reaction
This law explains what you feel on your hands after hitting a wall with your fist (you applied force to do this). The wall returns an equal and opposite force on your hands; thus the harder you hit, the more pain you feel.
The tendency of a body to remain in a state of rest or in uniform motion is referred to as _____.
ANSWER: Inertia
Inertia is a property of matter. It was Newton's 1st law of motion the showed the presence of inertia in a body at rest; or in another body moving in a straight line.
The Law of Inertia states that a body at rest will continue in the state of rest while a body in uniform motion will continue in a straight line; unless an external force acts upon it.
Newton's 1st Law of Motion is also referred to as the Law of Inertia
A change in the position of an object with reference to time is best described as _____.
ANSWER: Motion
Motion is simply defined as a change in the position of an object with reference to time.
For a body to be in motion, Force must act on it. It was Sir Isaac Newton that explained the relationship between the force(s) acting on a body and the motion of the body.
The saying 'what goes up on earth must come down' can be best attributed to _____.
ANSWER: Force
Force is a push or pull. The force acting on earth (gravitational force) is best attributed for pulling things/object down to earth. It was this that gave rise to the saying: 'What goes up must come down'.
We have _____ laws of Thermodynamics.
ANSWER: 4
There are 4 laws of Thermodynamics numbered from 0 through 3; that is
Which Scientist successfully discovered the theory of special relativity?
ANSWER: Albert Einstein
Albert Einstein successfully discovered the theory of special relativity in 1905. In his theory, Einstein determined that:
The laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum does not depend on the motion of all observers.
Generally, the relativity theory is often described with the analogy of a moving car
The scientific study of matter and the movement of matter through space and time is a concept of _____.
ANSWER: Physics
By Definition, Physic is the scientific study of matter and the movement of matter through space and time. It further explains how matter interact with each other.
10oF is associated with _____.
ANSWER: Temperature
oF stands for degree Fahrenheit which is a unit of temperature.
Another unit of temperature is oC which means degree Centigrade.
Also K which represents Kelvin is a unit of temperature.
