Intro to forces
what does force occur in and what is it measured in
occurs in pairs and measured in Newtons
what is a balanced force
2 equal forces pushing in the opposite direction
what 2 things could a force either be
Unbalanced and balanced
If you have double the net force on an object what happens to the acceleration
You will have double the acceleration
Give an example of Newton's third law
The action of a rocketship is the fire that's pushing it up and the reaction is the rocketship going up
How many forces are there and what are they
4; Friction,gravity,normal,netforce
what are balanced forces equal in
size and direction
if a force has a vector what does that mean
It means that it has strength and direction
If I push a 80,000 kg plane and a 4.5 G paper airplane with equal amount of force which will have a higher acceleration and which will have a lower acceleration
plane will have higher acceleration and paper airplane will have lower acceleration
If a back pushes a ball to the right what is the reaction
The ball pushes it back to the left
what 2 things give force to an object
push and pull
what should you do to find the Netflix and an unbalanced object
You should subtract the forces that are going to opposite way of each other
give an example of Newtons first law
Ex- a car that's moving stops because of a wall that it hits
what does the equation F=MA really mean
A larger mass requires a larger force to change the motion of the object and the larger force causes larger acceleration
What is Newton's 3rd law
Every action has an equal and opposite reaction
Give some ways an object can accelerate
start moving
move faster
stop moving
move slower
change direction
What should did you find the next force in a balance project
You add the two opposing forces
What is Newton's first law also known as
law of inertia
what is the format we use to find Force and acceleration
F=MA
F/M=A
What is Newton's 3rd law also known as
as the law of action and reaction
Explain what normal force, friction, gravity, and net force is
Friction- opposing Force created by two objects against each other
Gravity- pulls all objects in the universe toward one another
Normal- support Force exerted upon an object that is in contact with another stable object
Net force- overall or combined forces acting on an object
contrast unbalance forces and balance forces
balance; no movement, equal forces, no acceleration
unbalance: moving;has exeleration; not equal forces
What is Newton's first law
An object check that is in rest stay rest and the object in motion will remain in motion unless acted upon by an unbalanced force
What is Newtons 2nd law
The acceleration of an object depends on the net force acting on the object and the mass
What happens when an object exerts a force on another object
The second object exerts a force equal and strength and opposite and direction on the first object
