the resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest).
b)
a motion along a straight line, and can therefore be described mathematically using only one spatial dimension.

What is motion
a)
can also be defined as a continuous change in the position of an object.
b)
The equilibrium position is the position the object will attain when the force acting on it is zero. This type of vibration is called "whole body motion", meaning that all parts of the body are moving together in the same direction at any point in time.
c)
a quantity or phenomenon that has two independent properties: magnitude and direction.
75.
What is velocity
a)
is the speed of an object plus its direction.
b)
a way of measuring how quickly something is moving or being done, or something moving fast. An example of speed is a car being driven 45 miles per hour. An example of speed is someone cleaning a room in 10 minutes.
c)
a form of motion in which an object or particle (called a projectile) is thrown near the earth's surface, and it moves along a curved path under the action of gravity only. The only force of significance that acts on the object is gravity, which acts downward to cause a downward acceleration.
76.
What is a vector
a)
a quantity or phenomenon that has two independent properties: magnitude and direction.
b)
can also be defined as a continuous change in the position of an object.
c)
is the resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest).

In the 1960's, there was a drug called thalidomide. When the medication was being tested, only a few people were tested, however they were given the drug many times, over a long amount of time. Thalidomide was considered safe since there were no major, long-term effects on these few patients. Thalidomide was marketed as a drug to help pregnant women avoid morning sickness and nausea. When these women had their children, however, the babies were born with severe birth defects and malformations. Thalidomide is a very famous case study of why it is so important to have ___________ in scientific research.
