Newton's Laws of Motion
This Law of Motion states that an object at rest or at constant speed (linear) remain at rest or constant speed (linear) unless acted upon by an unbalanced force.
What is Newton's First Law of Motion?
The weight of an object is also called... and is measured in these units.
What is the gravitational force/force of gravity? What is Newtons?
Friction is the force caused by... and affects motion by...
What is "rubbing of two materials" and "opposes motion/slows things down"?
Having no net force and no acceleration means this about the forces on an object.
What is "opposite forces balance each other out"?
These are the five kinematic variables.
What is vi, vf, a, d, and t?
This term refers to an object's resistance to a change in motion. based SOLELY on an object's mass.
What is inertia?
What is the applied force?
This is the formula to (typically) calculate the frictional force.
What is "Ff=µ FN"?
If an object's scale reading is greater than the weight of the object, the object's acceleration and net force is in this direction.
What is "to the right"?
The component formulas use these two trigonometric functions for vectors at an angle.
What is sine and cosine?
This Law of Motion refers to two forces which are equal in magnitude but opposite in direction upon contact of two objects.
What is Newton's Third Law of Motion?
This force caused by any surface which provides support.
What is the normal force?
μ is...
What is "the coefficient of Friction"?
A 5000-kilogram truck drops 15 kilograms of cargo that was on it when it speeds up. The inertia of the truck-cargo system will... (increase, decrease, remain the same)
What is "inertia decreases"?
The horizontal acceleration is ... so the horizontal velocity (increases, decreases, or remains the same)
What is "0 m/s2"? What is "remains the same"?
Newton's Second Law of Motion states...
What is "a net force makes a mass accelerate"?
This relationship is true on level, horizontal surfaces.
What is "Fg = FN"?
This is the difference between static and kinetic friction.
What is "static means at rest and kinetic means moving"?
A golden retriever and a chihuahua bump into each other at a dog park. Compared to the magnitude of the force of the golden retriever on the chihuahua, the magnitude of the force of the chihuahua on the golden retriever is... (greater, less than, the same)
What is "the same"?
The vertical acceleration is ... so the vertical velocity (increases, decreases, or remains the same) in the downwards direction.
What is "9.81 m/s2"? What is "increases"?
These are the two ways to determine net force.
What is "the sum/difference of forces OR a=Fnet/m"?
This force is the only force split into components for inclined planes.
What is "Fg, the gravitational force/weight"?
An object moving at constant speed experiences an applied force of 33 newtons. Determine the amount of frictional force acting on the object.
What is "33 newtons"?
A golden retriever and a chihuahua bump into each other at a dog park. Compared to the magnitude of the acceleration of the chihuahua, the magnitude of the acceleration of the golden retriever is... (greater, less than, the same)
What is "less than"?
A 10-kilogram block starts from rest and accelerates at a rate of 1.1 meters per second squared. How long did it take the block to travel 7 meters?
What is "3.57 seconds"?
