Physics 1
What is Scalars?
Have magnitude but do not have direction.
for example 2kg
What is acceleration?
When the car begins to move, its speed increasing, this speeding up is called acceleration.
What is Vectors?
Have both magnitude and direction.
for example 20 m/s to the east
What is gravitational acceleration?
The acceleration during free fall is called gravitational acceleration.
g=9,8 m/s2
What is circular motion?
A car moves in a circular path with constant linear speed. This type of motion is called circular motion.
What is Tangential acceeleration's formula?
a=v/t
What is motion?
Motion is the phenomenon in which an object changes its position with respect to time.
What is free fall?
A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall
Write free fall's three formula?
1)h=1/2gt2
2)vy=gt
3)v2y=2gh
What is circulat motions formula?
ө=S/r
What is angular speeds formula?
w=2p/T
What is Centripetal acceleration?
a=v2/R
What is angular speed?
Angular is a pseudovector representation of how fast the angular position or orientation of an object changes with time.
What is Centripetal acceleration?
Any object in rotational motion due to any centripetal force such as due to gravitation, experiences an equal and opposite centrifugal acceleration.
Centripetal Acceleration = Centripetal Force / Mass of the revolving body
