Laws of Motion
1st Law of Motion
What is the Law of Inertia?
Joule
What is the SI unit of Work?
Newton (as a unit)
What is the SI unit of Force?
9.8 meters per second squared
What is the value of acceleration due to gravity?
object moves along a circle at constant speed.
What is uniform circular motion?
The property to resist a change in motion or rest
What is Inertia?
object moves a distance parallel to force applied
What is Work?
meter per second squared
What is the unit for acceleration?
distance of the lifted object from the ground to its final position.
what is height?
the inward force acting on an object moving in a circular path
What is centripetal force?
force opposing relative motion
What is Friction?
a larger unit of power
What is horsepower?
acceleration is directly proportional to force and inversely to mass
What is the 2nd law of motion?
1/T
How do you calculate frequency (for uniform circular motion)?
the rotating object's velocity
What is tangential velocity?
forces involved in the Law of Interaction
What are action and reaction forces?
Smaller unit of work
what is Ergs?
v2/r
How do you compute centripetal acceleration?
number of turns/revolutions in a specific time
What is frequency?
quantity of an object
What is mass?
amount of work done per unit time
What is Power?
for every action, there is an equal and opposite reaction.
What is the Law of Interaction/ 3rd Law of Motion?
time needed to complete one revolution
What is period?
