Describing Motion Flashcards
(22 cards)
It is the changes in position
Motion
The sum of all points of position where the object travels
Distance
What is the equivalent of 1km in miles?
0.621 miles
How many cm there is in a meter?
100 centimeters
What is the shortest way where the object travels?
Displacement
At rest type of energy
Static
Including in his type of motion are the magnitude, direction and units
Kinematics
This type of measurement contains magnitude and units
Scalar
Refers to expressing a number as a product of any number between 1 and 10 to the 10th power
Scientific Notation
This type of measurement includes both magnitude and units but an addition of direction
Vector
He’s a scientist born in 1643
Isaac Newton
How will compute the force of an moving object?
F = m•a
Force is equal to mass multiplied by acceleration
How will you compute an acceleration of an object if the problem relays the force and mass of an object?
a =f/m
It describes motion in terms of displacement, velocity, and acceleration
Kinematics
It refers to the location of an object with respect to a frame of reference
Distance
Tendancy of a body to maintain it’s state of rest or motion
Inertia
The force of gravity on an object
Weight
Property of an object that specify how much resistance an object exhibits to change
Mass
Enumerate Newton’s Law of Motion
- An object at rest will remain at rest unless acted upon by a net force and an object in motion will remain in motion unless acted upon by a net force
- Force is equal to mass multiplied by acceleration
- For every action, there is an equal and opposite reaction.
This refers to the motion of objects in an inertial reference frame
Newton’s Law
What is the difference between weight and mass? Elaborate your answer
Mass is unchanging, your mass is equal here on earth as so in the vacuum of space or in the surface of the moon
But weight depends on gravity, your weight is different in the surface of the moon, compared here on earth
What is one way to calculate the mass of an object?
By mutiplying the volume and density of an object, you’ll get the mass :>
Mass = volume x density
