How To Calculate Acceleration

YouTube Preview Image

Description

A detailed tutorial on how to calculate an object’s acceleration.  A step by step guide on solving for an object’s acceleration.

Overview

Acceleration is defined as the change in velocity over the change in time.

a = \frac{\Delta v}{\Delta t}

Velocity is measured in meters per second while acceleration is measured by meters per second per second.

\frac{m}{s * s} = \frac{m}{s^2}

Acceleration is also expressed as the derivative of velocity.

Newtons 3rd Law of Motion Explained

Description

A detailed explanation of Newtons 3rd Law of Motion: Reciprocal Actions. Step by step tutorial including several examples of how to apply Newtons 3rd Law of Motion: Reciprocal Actions for reference.

Overview

Newton’s third law basically states that for every action there is an equal and opposite reaction.  This also applies to forces.  Whenever there is a force, there is a reaction force equal in magnitude in the exact opposite direction.

A detailed tutorial on the solving of Polynomial. Step by step tutorial including several examples of how to solve Polynomial for reference.

Overview

In mathematics, a polynomial is a finite length expression constructed from variables (also known as indeterminates) and constants, by using the operations of addition, subtraction, multiplication, and constant non-negative whole number exponents. For example, x2 − 4x + 7 is a polynomial, but x2 − 4/x + 7x3/2 is not, because its second term incorporates division and because its third term contains a fractional index.

How to calculate the force of friction on an incline plane?

Description

A detailed tutorial on the solving for Friction on an Incline Plane. Step by step tutorial including several examples of how to solve for Friction on an Incline Plane for reference.

Overview

The force of friction, F_f, can be defined as \mu multiplied by the normal force, N.
F_f = \mu * N

N is equal to the opposing force perpindicular to the surface.  In the case of an inclined plane, the opposing force to the surface would be the perpindicular component of gravity acting on the object.  To get this component, you must complete the triangle and solve for the normal force.  Once you have the normal force you can multiply by the coefficient of friction to get the force of friction.

Description

A detailed tutorial on the solving of Newtons 1st Law of Motion: Law of Inertia. Step by step tutorial including several examples of how to solve Newtons 1st Law of Motion: Law of Inertia for reference.

Overview

Newton’s first law of motion states that an object at rest will remain at rest while an object in motion will remain in motion if there are no external forces acting on the object.  This means that if you dropped a ball in deep space where there are no external forces in action, the ball would remain where you dropped it and would not fall to the ground.  This also means that if you threw that ball in space, the ball would not slow down until it hit something or it encountered some other force to change its velocity.

Newtons 2nd Law of Motion: F=ma

Newtons 2nd Law of Motion Explained

Description

A detailed tutorial on the solving of Newtons 2nd Law of Motion: F=ma. This video gives several detailed examples of how to use Newton’s 2nd law.

Overview

Newton’s second law states that force applied to a body produces a porportional acceleration expressed by the formula

F = m \times a,

where F is the force applied, m is the mass of the body, and a is the body’s acceleration. If the body is subject to multiple forces at the same time, then the acceleration is proportional to the vector sum (the net force):

F_1 + F_2 + \cdots + F_n = F_{net} = m \times a
