LESSON 3 Flashcards
if an object changes its position with respect to its surroundings with time
motion
If an object does not change its position with respect t its surroundings with time
Rest
if it undergoes equal displacement in unequal intervals of time
non-uniform motion
is a scalar quantity that refers to “how much ground an object has covered” during its motion
distance
is a vector quantity that refers to “ how far of place an object is” difference between your final and initial
Displacement
actual length covered by moving body irrespective the direction
distance
shortest distance between initial and final position
displacement
is a scalar quantity that represents the distance traveled by an object in a given unit of time
speed
is defined as the total path traversed by an object divedd by he total time taken for the motion to take place
average speed
is the speed recorded at a specific time or instant
instantaneous speed
is a vector quantity that represents the rate change in displacement
velocity
constant velocity
vector
for velocity itrefers to how fast the object is moving
magnitude
north, south, east, west, and the positive or negative sign
direction
moving constant but does not have continuous velocity because its direction changes
acceleration
refers as the change in position(or displacement) over the time of travel
average velocity
an object must have constant speed in a constant direction
constant velocity
is the rate of change of velocity with time
acceleration
when a body moves along s straight line and its velocity increases by equal amounts in equal intervals of time then the motion is called?
uniformly accelerated motion
an object that is falling under the sole influence of gravity
free falling bodies
