LESSON 3 Flashcards
It states that the unbalanced force on a particle causes it to accelerate.
Newton’s Second Law of Motion
This is referred to as the equation of motion and is one of the most important formulations in mechanics.
Newton’s Second Law of Motion Equation or F = ma
It is the mutual attraction given by any two particles.
Newton’s Law of Gravitational Acceleration
What is the universal constant of gravitation?
66,73 10^-12 m^3/kg s^2
It is a property of matter that provides a quantitative measure of its resistance to a change in velocity.
Mass
It is an absolute quantity.
Mass
It is a force that is caused by the earth’s gravitation.
Weight
It is not absolute; rather it depends on the altitude of the mass from the earth’s surface
Weight
In theSI system, the mass ofa body is specified in ____________ and the weight in __________.
- kilograms (kg)
- Newtons(N)
In the FPS system, the weight is specified in __________ and the mass in ____________.
- pounds (lb)
- slugs (slug)
When more than one force acts on the particle, the resultant force is determined by a ____________________.
vector summation of all forces
It identifies the magnitude and direction of the vector ma (right-hand side of the equation).
Kinetic diagram
Whenever the equation of motion is applied, it is required that measurements of the acceleration be made from a_______________.
Newtonian or inertial frame of reference
It does not rotate and is either fixed or translates in a given direction with a constant velocity (zero acceleration).
Newtonian or inertial frame of reference
n mechanics a force 𝐅 does ______ on a particle only when the particle undergoes a displacement in the direction of the force.
