The law of motion that causes a tendency of objects in motion to stay in motion and at rest to stay at rest.
What is the interaction between an object and its environment?
The name for Newton's First Law of Motion
What is Law of Inertia?
The Second Law of Motion
What is Force equals mass times acceleration (F = ma)?
The Third Law of Motion
What is for every action, there is an equal and opposite reaction?
The weight of an object
What is the magnitude of the gravitational force on the object and is equal to the object's mass times acceleration due to gravity?
The property in which Force can act through
What is contact and distance?
The state of an object at rest unless acted upon by external force
What is remain at rest?
The equation F = ma represents
What is Force equal to Mass times Acceleration?
The push wall doesn't push back when pushed against because
What is the wall pushing back with an equal and opposite force?
The weight expressed in an equation
What is Fg = mag?
Where Fg is weight equal to Mass times (x) ag is the magnitude of the acceleration due
to gravity or what I’d like to refer to as ‘Free-Fall Acceleration’
What is a Free-body diagram?
The acceleration and measure of inertia
What is the change in an object's velocity and mass?
The units of Mass, Acceleration, and Force in the SI system
What is Kilograms (also abbreviated as kg), meters per second squared (m/s2), and Newtons (N)?
The equation of Newton's Third Law
What is FA = -FB?
(Where A and B represent Objects)
The normal force
What is the force that acts in a direction opposite to the direction that is perpendicular to the surface of contact?
The formula for calculating acceleration given the change in velocity and the time take for the change
What is acceleration = change in velocity divided by time?
True or False. A book remaining stationary on a table until an individual pushes it is an example of Newton's First Law of Motion
What is True?
The book sits on top of a desk with 3 kg of weight, the normal force that is exerting on the book is
What is 29.4N?
Math:
F = ma
Fn - Fg = 0
Fn - 29.4 = 0
Fn = 29.4 N
Fg = mg
(3)(9.8) = 29.4 N
The movement of jumping off the ground represents Newton's Third Law of Motion
What is True?
The law of gravity
What is the force that causes things to drop to the ground?
The force that pulls a meteor into Earth's atmosphere
What is Field Force?
The passengers move forward in their seats when a car suddenly stops
What is Inertia?
The student is pushing a 30 kg box with 300 N of force, the acceleration of the box is
What is 10 m/s2 (Remember the Units!)
F = ma
300 = (30)a
300/30 = 10
The ice skater that weights 72 kg pushes a large block of ice weighing 200 kg. The force exerted by the ice skater is 90 N, the calculation for the acceleration of the skater and the block of ice after the push is
What is skater = -1.25 ms-1 and block of ice = 0.45 ms-1
Math For Ice Skater:
Fs (Force of Skater) = 90N
F = ma
Fs = msas
as = Fs/m2
a2 = -90/72
a2 = -5/4 = -1.25 ms-1
Math for Block of Ice:
F = ma
FB = mBaB
aB = 90N/200 kg
aB = a/20 = 0.45 ms-1
The Friction of a force is
What is the resistive force that governs in a direction that is opposite to the direction of the relative motion of two contacting surfaces?
