Describe the difference between a balanced and an unbalanced force.
One has a net force in one direction while another cancel each other so there is no acting force.
One exerts more force to the other while one creates more contact rather than exert forces. The sides of forces create contact to each other to pull the object to one side
One has a greater net force than the other one. While the other has a less acceleration force.
Both of them are similar.
What is Newton's first law of motion?
Forces act in pairs: For every action there is an qual but opposite reaction.
The acceleration of an object is equal to the net force on an object divided by the mass of the object.
An object in motion will remain in motion and an object at rest will remain at rest unless there's net force acting on the object.
A strong force will exert more force onto the pushing side to the object unless there is something blocking the object to continue to move.
Your class and your parents are playing tug-of-war. Your team pull with a force of 150N and your parents are pulling with a force of 220N, what is the net force?
370N
35N
185N
70N
50N
If a 3600 kilogram vehicle accelerates at a rate of 9 meters per second, what is the force the engine applied to the car?
400N
1200N
32400N
26000N
What is the unit of a force, and what is "1"N unit equivalent to?
A Newton (N). 1N= 1kg X M/s^2
A (N). 1N= 1Kg x 100 : M/s^2
A Pascal: 1P=1000: 1N
What is an example of Newton's third law of motion?
Kicking a ball
Pulling a magnet off a fridge
Catching a basketball and a tennis ball
Strike the ground by an object.
What are the specs of Coupled forces/Action-reaction pairs?
They have equal balanced force.
They consist opposed forces on to together.
They have equal but opposite forces.
They have opposite reaction forces.
(Tricky question): Newton's third law example: When you strike the ground with your foot, you exert a force on earth, and Earth exerts equal but opposite force on you, propelling you forward.
So if you exert a force on earth, how come earth doesn't also move?
Because although the force is split equally along the area of the earth, regardless of how powerful the force is (except for earthquakes), it's unable to split powerfully for everyone to sense.
Because of the force is concentrated in one place, so that the other place couldn't make the earth moves.
Because the force that you exerted couldn't affect the earth entirely, the earth coulnd't move because the force that you exerted is uncompareable with the mass of the earth, still the force existed.
The following equations are all existed in Newton's law of motion EXCEPT for?
A=FV-IV : TIME
M=MxV
A= NF/M
NF= M x A
NF=F-F
