Study These Flashcards
A

C2=a2+b2

C= -/a2+b2

25
_________________ Body’s resistance to change its present condition. -a body at rest tends to stay at rest. -a body in motion tends to stay in motion
INERTIA
26
________________ Quantity of a body’s matter. -directly related to inertia -the greater the _____, the greater the body’s resistance to change its present condition.
MASS
27
______________ The pushing or pulling effect one body may exert on another. -this is a vector. -Resultant ______ vectors can be calculated
FORCE
28
___________=mass x velocity WEIGHT. 100 Mdash Child=30 kg. 15s Adult=90kg. 15s Childs momentum = 200kg x m/s Adults momentum = 600kg x m/s
MOMENTUM
29
What are Newtons three Laws of Motion? These apply to all matter in the Universe EXCEPT- complex systems, subatomic particles
The Law of Inertia The Law of Acceleration The Law of Action and Reaction
30
___________________ -a body will continue in its state of rest or uniform motion. -unless acted upon by an external force.
THE LAW OF INERTIA
31
_________________ The acceleration of a body is proportional to the force imparted on it and inversely proportional to its mass A= f M F=m x a
THE LAW OF ACCELERATION
32
The measure of Force is called _____________
NEWTON
33
__________= force required to accelerate one kilogram of mass at a rate of one meter per second squared
NEWTON
34
you push me, i am going to push you back. This is an example of which of Newtons three laws?
THE LAW OF ACTION AND REACTION
35
To every action, there is an equal and opposite reaction.
THE LAW OF ACTION AND REACTION
36
All three laws (newtons laws) can also be applied to ______________(__________) Motion
ROTATIONAL (ANGULAR)
37
Force in angular motion must be changed to _________
Torque
38
______ = Force x Lever arm -Force necessary to rotate a body -Lever arm = the shortest distance from the center of the body’s axis..... To the line of application of the force.
TORQUE
39
______________ A rigid body with an axis of rotation All have; - Axis of rotation (A) - A resistance (R) - A force (F)
LEVER ARMS
40
_________________ Moment (Effort) Arm The Distance between the axis of rotation (A) and the Force (F)
FIRST CLASS LEVER
41
F X FA = R X RA | Stands for what ?
FORCE X FORCE ARM = RESISTANCE X RESISTANCE ARM
42
What is the formula for Mechanical Advantage?
FORCE ARM —————— RESISTANCE ARM
43
