what is force?
Force is a vector, so it has direction and magnitude
Newton’s first law and ex
An object remains at rest and an object motion maintains its velocity unless it experiences net force
Example is a person in a car
Define vector
Have both magnitude and direction
What happens two momentum during a collision
Momentum is the same as momentum before the collision
Define an explosion collison
A special type of inelastic collision an example is dynamite
How is force calculated? Formula.
Force equals F=mxa
Newtons second law
And ex
The unbalanced force on an object equals the object mass times its acceleration
an example is pushing an empty shopping cart and a full shopping cart
What is momentum
The quantity of motion an object has
What does conservation mean?
To keep from wasting or losing; preserve
force of drag =
Balanced force meaning it will be equal to drag force
What is the unit used to measure forces?
NEWTONS N
New third law and ex
For every net force is an equal and opposite reaction force
Ex. Person pushing a wall.
What do we use to define the letter P?
Impetus
What things in science are conserved
Energy mass and momentum
What’s the difference between contact and noncontact force?
Contact requires physical contact between objects and non-client does not require physical contact
Define balanced force
Force that’s equal in magnitude and opposite in direction
How was momentum Calculator
P=mxv
Define elastic collision
When objects collide and bounce off each each other without changing shape or sticking together
Define inertIa
The Tendency to resist change in motion
Define unbalanced force
Forces that are not equal
What unit is used to measure momentum?
Kg x m/s^2
Define inElastic collision
When objects collide and stick together or change its shape
