Physicists use other mathematical relations like graphs and tables in order to :
Predict the relation between certain physical quantities .
Understand practical results.
Describe the physical phenomena in an easier way.
All the previous
It is the speed by which the object moves when it covers equal distances at equal periods of time
Irregular (non-uniform)
Positive uniform acceleration
Regular (uniform) speed
Motion
It is an acceleration by which an object moves in a straight line when its speed decreases by equal values through equal periods of tim
Irregular (non-uniform)
Positive uniform acceleration
Regular (uniform) speed
Negative uniform acceleration
An object started its movement from rest and its speed changed to 36 km/h. in 10 seconds, calculate the body acceleration and state its type
1 m/sec , it's type accelerating motion
1 m/sec , it's type decelerating motion
1 k.m/h , it's type accelerating motion
1 m/sec2 , it's type accelerating motion
Acceleration is
vector quantity whose unit is m/s
scalar quantity whose unit is m/s
scalar quantity whose unit is m/s2
vector quantity whose unit is m/s2
The shortest length covered by the object in a fixed direction is called
distance
displacement
acceleration
speed
