Students in a physics lab are observing the swings of a pendulum. They are studying the variable that affects how long the pendulum will take to complete 10 swings, Select the variable that will
most likely NOT affect the time to complete 10 swings.

a)temperature of the room
b) mass of the pendulum
c) length of the pendulum
d)angle of initiation of the swing

Iwould sure like to answer your question but i honestly just don’t know

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

The force is push or pull
