When scientists are trying to understand a particular set of phenomena, they often make use of, in a scientific sense, a kind of analogy or mental image of the phenomena in terms of something we are familiar with called:
(a) model
(b) theory

Usually a model is relatively simple and provides a structural similarity to the phenomena being studied, whereas a more broader, more detailed, and can give quantitatively testable predictions, often with great precision is called:
(a) model
(b) theory
(c) law
(d) principle

A quantity such as velocity, which has direction as well as magnitude, is:

Many quantities such as mass, time, and temperature, have no direction associated with them. They are specified completely by giving a number and unit called:
(a) vectors
(b) scalars

(d) speed

Motion taking place in two dimensions is:
(a) projectile motion

The length of the resultant can be measured with a ruler and compared to scale.
Angles can be measured with a protractor. This method is known as the:
(a) sum of squares

(c) tail-to-tip
(d) tip-to-tip

A vector V that lies in a particular plane can be expressed as the some of two other vectors usually chosen to be along two perpendicular directions is called:
(a) vectors
(b) scalars
(c) resultants
(d) components

Any kind of a push or a pull on an object is:
(a) force
(b) vector
(c) scalar
(d) distance

Every body continues in its state of rest or of uniform speed in a straight line unless acted upon by a nonzero net force is:
(a) Newton’s zeroth Law of Motion
(b) Newton’s First Law of Motion
(c) Newton’s Second Law of Motion (d) Newton’s Third Law of Motion

A measure of the inertia ofa body is:
(a) weight
(b) velocity
( c) distance
(d) mass

The acceleration of an object is directly proportional to the net force acting on it and is inversely proportional to its mass. The direction of the acceleration is in the direction of the net force acting on it. This is Newton’s:
(a) Zeroth Law of Motion
(b) First Law of Motion
c) Second Law of Motion
(d) Third Law of Motion

In SI units, with the mass in kilograms, the unit of force is called the:
(a) Newton
(b) Galileo
(c) Pound
(d) Erg

Whenever one object exerts a force on a second object, the second exerts an equal and opposite force on the first. This is Newton’s:
(a) Zeroth Law of Motion
(b) First Law of Motion
(c) Second Law of Motion
(d) Third Law of Motion

The force of gravity on an object is called its:
(a) mass
(b) weight
