What is Law of motion?
An electronic mechanical delay
A summation of forces
A science that describes the rule of motion.
"A body will maintain a state of rest or constant velocity unless acted on by an external force that changes the state."
Is which Law of Motion?
Newton 1st law of motion
Newton 2nd law of motion
Newton 3rd law of motion
Law of gravitation
The image above is describing which law of motion?
law of gravitation
law of acceleration
law of action-reaction
law of inertia
Which of the below is NOT a type of motion?
Oscillatory motion
Apex motion
Angular motion
Linear motion
fluid motion
Fill in the blanks.
The 2nd Law of Motion mentions that the change in the state of a body or the acceleration is proportional to the _________ of the force and the direction in which it is applied.
weight
height
magnitude
Contact force, friction forces, muscle forces and elastic forces are _______________ type of forces.
external
internal
MOMENTUM is defined as the product of mass (m) and .......
velocity
weight
mass
acceleration
In Force Summation, in order to gain maximum momentum, the forces need to be generated by....
Movement does not have to achieve correct timing
Using as many segments of the body as possible
Movement must be in the correct sequence, using the large muscles first followed by smaller muscles last (but the smaller muscles will be faster)
Movement must be through the greatest range of motion (ROM),not a limited ROM
External forces come from outside the body
True
False
Impulse = F x _____
acceleration
magnitude
time
velocity
Principles of Impulse-Momentum state that....
impulse = change in momentum
impulse = force x time
momentum = mass x velocity
F = m x a

law of inertia
law of gravitation
law of reaction-action
law of acceleration
