Physics : speed , velocity , acceration definition
Average acceleration
The change in velocity divided by the change in time.
Acceleration
The rate at which velocity is changing. It applies to decreases/ increases in speed and/or change in direction.
Average speed
Total distance traveled divided by the total time it takes.
Average velocity
Total distance traveled divided by the total time it takes.
Instantaneous speed
Velocity an object is moving right at that instant.
Instantaneous velocity
an object is moving right at that instant.
Pythagorean theorem
c2 = a2 + b2
Negative acceleration
object is slowing down
Vectors
quantities represented by an arrow that has both direction and magnitude.
Scalars
quantities with just magnitude (numerical value) alone.
Resultant vector
result of a + b
Magnitude
the size or length of something.
Displacement (vector)
the straight line distance between the two points.
Terminal velocity
top speed you can reach
Velocity
Measure of distance traveled in a given period of time with a direction.
Speed
Measure of the distance traveled in a given period of time.
Constant acceleration
A moving object that is not changing speed or direction.
Constant velocity
An object moving at a constant speed and in a constant direction.
Constant speed
An object moving at a constant speed.
Distance (scalar)
Distance (scalar)- measurement of the actual path covered.
