Module 2 Representing Motion Review

Besides knowing the location of an object, what else must be known to describe its motion along a straight line?

• The forces acting on the object

• The energy changes of the object

• The acceleration of the object

• The time it takes for the object to move

How is a time interval mathematically represented?

• ∆t = tf - ti

• ∆t = tf + ti

• ∆t = tf / ti

• ∆t = tf x ti

What is the purpose of a position-time graph?

• To show the speed of an object

• To show the acceleration of an object

• To show the position of an object at different times

• To show the distance traveled by an object

To show the distance traveled by an object

• The objects are at the same position

• The objects have the same speed

• The objects have the same acceleration

• The objects have the same distance traveled

Which object is moving faster?

• Object A

• Object B

• Both A and B are moving at the same speed.

• You can't tell that information from the graph.
