1-D Kinematics
What is Kinematics
The science of describing the motion of objects using words, diagrams, numbers, graphs and equations
What is Newton's First Law
sometimes referred to as the law of inertia, describes the influence of a balance of forces upon the subsequent movement of an object.
What is Vector diagrams
Depict a vector by use of an arrow drawn to scale in a specific direction.
What is Momentum
What is Potential energy
The stored energy of position possessed by an object.
What is Scalars
Quantities that are fully described by a magnitude alone.
What is Newton's Second Law
Acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
What is Vector Addition
A variety of mathematical operations can be performed with and upon vectors.
What is Impulse
These concepts are merely an outgrowth of Newton's second law as discussed in an earlier unit.
What is Kinetic energy
The energy of motion.
What is Vectors
Quantites that are fully described by both a magnitude and a direction.
What is Newton's Third Law
When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
What is the Pythagorean Theorem
A useful method for determining the result of adding two (and only two) vectors that make a right angle to each other.
What is Big T and Little F
A big Tevent is one that most people will consider traumati, such as a plane crash. A little T is is something more on a smaller scale, such as a lost of a pet.
What is Mechanical energy
The energy acquired by the objects upon which work is done.
A scalar quantity that refers to "how much ground an object has covered" during it's motion.
What is Force
Push or pull upon an object resulting from the object's interaction with another object.
What is a Projectile
An object upon which the only force acting is gravity. There are a variety of examples of projectiles.
What is collision
An interaction between two objects that have made contact (usually) with each other.
What is Watt
The standard metric unit of power.
A vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
What is Action-at-a-distance force
Those types of forces that result even when the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite their physical separation.
What is net force
The vector sums of all the forces that act upon an object.
What is Momentum Conservation Principle
One of the most powerful laws in physics is the law of momentum conservation. The law of momentum conservation can be stated as follows.
What is Power
The quantity work has to do with a force causing a displacement. Work has nothing to do with the amount of time that this force acts to cause the displacement.
