Units of measure
m/s
What is the units of measure for velocity?
This force is due to the gravity
Weight force or gravitational force
What is the difference between velocity and speed?
Speed is an scalar, velocity is a vector
This law is also known as the law of inertia
1st Newton's law
Equation for Force
m / s2
What is the units of measure for acceleration?
The force which is in the opposite sense to the motion of the object
Friction force
Kg is the unit of measure for....
Mass
What is the acceleration due to gravity on Earth?
9.81 m/s2
Equation for velocity or speed ?
v = x / t
Newton
What is the unit of measure of Force
This force must be represented usually following the trajectory in a free body diagram and there is a contact with the object when using that force
Compression force or pushing force
It is the energy that a body possesses by virtue of its movement, no matter if this movement is constant or accelerated
Kinetic Energy
It is the energy that a body possesses by virtue of its position (height) in relation to a reference plane
Potential Energy
Equation for Work
Work = Force * displacement
Joule
What is the unit of measure for work?
