How to calculate weight using newtons
First find weight as newtons by completing the equation: weight = mass x gravity. Weight is then divided by the amount of newtons in one pound: 4.5.
Got it
Acceleration of Gravity
This refers to how quickly an object falls when subjected to gravity. On Earth, objects in free fall will increase how quickly they fall by a rate of 9.8 meters every second.
Got it
Gravity
A force that pulls two objects with mass closer together. This decreases as objects move apart by the square of the distance between them. This is stronger on Earth than the moon.
Got it
Velocity
You can use this term when discussing how fast an object is moving.
Got it
Force
We use this term to refer to something that influence an object in a way that changes the object's motion or shape. This may result in acceleration.

Flashcard Content Overview

This set of flashcards was set up to give you the chance to review facts about energy. You'll also find cards that deal with force, velocity, speed and distance. You can review the acceleration of gravity and consider how to determine weight in newtons, along with the formula to calculate speed. Furthermore, working with these flashcards can allow you to focus on sedimentary, igneous and metamorphic rocks.

Speed Formula
Speed = distance / time
Speed
This refers to how great a change in distance you make in a given period of time.
Distance
We use this term to discuss how much total ground a moving object covers.
Energy
This can be considered as our ability to do work. It can be converted into matter and then back again. We measure this in joules.
Velocity Formula
Velocity = displacement / time
Acceleration
Objects possess this when they experience changes in velocity. It velocity increases, this is positive; if velocity decreases, this is negative.
Two gas stations are forty miles apart. You drive from one to the other in an hour. What was your average speed?
40 mph
Two gas stations are twenty miles apart. You drive from one to the other and back again in an hour. What was your average velocity?
0 mph
