newton
what is newtons first law?
an object in motion will stay in motion and an object in rest will stay in rest
what is motion?
the action or process of moving or being moved.
what is force?
a push or pull upon an object resulting from the object's interaction with another object
newton meter
The newton meter works by stretching a spring. As the mass being measured increases, the force downwards, due to gravity increases, stretching the spring further.
what is energy?
The capacity or power to do work
what is newtons second law?
force=mass*acceleration
in scientific terms?
change with time of the position or orientation of a body
how to measure force
using a newton meter
microscope
used to magnify small objects
how does energy affect you
Energy fuels your body's internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body's most important nutrient, helps facilitate the chemical reactions that produce energy from food.
what is newtons third law?
for every actions there is an equal and opposite reaction
motion example
Running, cycling, jumping, swimming, eating, drinking, playing, writing, typing, moving cars, and throwing a ball are all examples of motion.
forces uses in everyday life
We use force to walk on the road, to lift the objects, to throw a cricket ball, or to move a given body by some particular speed or direction.
thermometer
A thermometer is a device that measures temperature or a temperature gradient
what measures energy
Joules measure energy
example of newtons 3rd law
When a bullet is shot from a gun, the gun puts a force on the bullet that propels it forward. In the backward direction, the bullet exerts an equal force on the rifle
motion equation
F = ma
force equation
force= mass times acceleration
gram scale
to measure the metric weight of small objects
energy uses in daily life
electricity—all types of energy end uses. natural gas—space and water heating, clothes drying, cooking. heating oil
newtons first law example
a ball rolling down a hill will continue to roll unless friction or another force stops it
how to measure motion
dividing the distance covered by the time it takes to travel that distance.
forces effect on motion
They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving
bunsen burner
a type of gas burner that produces a safe, smokeless, hot, non-luminous flame that can be used for various scientific experiments
energy equation
E = mc2
