Newtons Laws
What is Newtons 1st Law?
the tendency of an object to resist changes in motion, unless acted on by a outside force
What is the Equation to find Acceleration?
A=F/M
Pushing a box with 100N to the left and friend pushes the box 100 N to the right.
What is balanced forces
No motion
Find the Centripetal Acceleration of the box with a velocity of 4 meters per second. the box also sits 2 meters from the center of the platform
A= V2/R.
A= 8m/s2
Draw a body diagram that best represents a cart slowing down as it travels to the right on a horizontal surface.
More Force going left because its slowing down, can be caused by friction/wind resistance.
What is Newtons 2nd Law?
states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleratio
What is the Equation to find Centripetal Acceleration?
You pull a box with 150N to the right and your friend pushes it in the same direction with 50N. Susan pushes the box to the left with a force of 100N
What is the box move to the right with 100N force
A 12 Kilogram block is sitting on a frictionless surface that has two forces applied to it. A force of 36 newtons to the right and a force of 12 newtons to the left.
What is the acceleration?
A=F/M
What is 2m/s2 to the right
Draw a body diagram that best represents you as a passenger in a car and you lift up from your seat.
Force going down
What is Newtons 3rd Law?
For every action, there is an equal and opposite reaction
What is the Equation to find Centripetal Force?
F = (M x V2)/R
When an object, such as a helicopter is moving at a constant speed and maintaining constant elevation, is in equilibrium, the net force is.....
What is Zero?
The Distance between two objects is doubled, How does that affect the gravitational force between them?
It is Quartered
Draw a body diagram that best represents a helicopter climbing up at a constant rate.
Force going up
Which Newton Law is Demonstrated....You are standing on a bus. The bus suddenly stops, but your body continues to move forward?
What is Newtons first law of Motion
What is the equation for frequency?
F = 1/T
A satellite is moving at constant speed in a circular orbit about the moon.
The net force acting on the satellite is directed towards where?
The moon, the gravitational force pulls it to the moon.
A football player throws a football Horizontally. How can we describe the balls motion in response to its speed. (Horizontal Speed and Vertical Speed)
Its vertical speed Increases, its horizontal speed remains the same.
Draw a body diagram that best represents a car speeding as it travels to the left on a horizontal surface.
More force going to the left
Which Newtons Law is Demonstrated.....
A paddle board moves forward through the water because you pull the oar backwards?
What is Newtons 3rd Law of Motion?
What is the Equation to find Gravitational Force?
F = G(M1xM2)/R2
For every action, there is an equal and opposite reaction
What is Newtons third law of motion
Based on the Universal Law of Gravitational, how can we decrease the gravitational force between two objects?
Decrease one mass, decrease both masses, or increase the distance between the two Objects
Draw a body diagram that best represents a plane that is in equilibrium in the air.
Even on all sides
