lab safety
you should do this if your hair is past your shoulder before entering the lab.
what is a hair tie?
A educated guess
Hypothesis
An object at rest
Remains at rest
the formula for mass acceleration
F=MA
For every action there is in equal opposite reaction true or false ?
TRUE
when in the lab you must have on ?
safety goggles
The 4th step of scientific method
Experiment
objects change their state of motion
only when net force is applied
As the mass of an object increases
the acceleration decreases
Formula for newtons 3rd law
F A = F B
this is never allowed in the lab
Never eat food, drink beverages, chew gum, apply cosmetics (including lip balm), or handle contact lenses in the laboratory.
The number of steps in scientific method
6
object in motion
stays in motion
one way to solve a problem with this formula
Triangle method
Another law
Law of inertia
Attire that should be worn in lab
no shorts, capris, skirts or ripped jeans. Shirts and tops must cover the shoulders and upper torso. Long hair should be tied back. Loose jewelry or neckwear (such as ties, shawls or scarves) that hang outside the lab coat is not permitted , closed toe shoes.
all the sciences that require scientific method
chemistry, physics, geology, and psychology.
This net force is required to keep a 500 kg object moving with a constant velocity of 10ms
0 N
We know that force = mass x acceleration
15N = 25Kg x accenration
Acceleration =15/25
what is the correct answer?
0.6 ms
the creator of this law
isaac newton
When testing for odors you should
raise your hand above the container then waft the air towards your nose
List all six steps of the scientific method.
What is Question, Hypothesis, Experiment, Observe and Record, Analyze Results, Share Results.
It’s the formula for this law
p=mv
The three forms of acceleration found on a roller coaster
What is increase speed - down hill, decrease speed - uphill, change direction - loop/corner
A high school student hits a nail with a hammer. During the collision, there is a force on...
What is on the nail and also the hammer?
