G6-Position and Motion

Position & Motion

What is the difference?

Position:

●

Describes the LOCATION of an object.

●

Can be described using UP, DOWN, NORTH, SOUTH,

EAST, or WEST.

●

A position is compared to a Frame of Reference

Multiple Choice

To determine if an object has changed position, you need to know its position relative to another object. _______________

• True

• False

Multiple Choice

The position of a runner in a race changes as time passes. What could a reference point to describe the change in position? 

• the starting line
• the runner’s speed
• the runner’s right foot
• another runner

Define Motion:

● is the change of position over time.
● When describing motion, the answer depends

on the position and motion of the person
observing you.

Example: Sitting at your desk, are you in motion?

Sitting in a car, are you in motion?

Multiple Choice

When an object’s distance from another object is changing,

• it is in motion.

• it is speeding.

• it has a high velocity.

• it is accelerating.

Match

Match the word with the correct definition.

• Friction

• Gravity

• Pull

• Push

• Motion

A force that resists (slows down or stops) the motion of two surfaces sliding across one another

The force that causes objects with mass to attract to one another

A force that when applied, moves an object towards you

A force that, when applied, moves an object away from you

A change in position of an object

• A force that resists (slows down or stops) the motion of two surfaces sliding across one another

• The force that causes objects with mass to attract to one another

• A force that when applied, moves an object towards you

• A force that, when applied, moves an object away from you

• A change in position of an object

Reference Points:

● Reference Points are:

○

Nonmoving points

○

Used to locate and describe the motion of an object

○

Used to describe objects to the north, south, east, or

west

○

A comparison between moving and nonmoving

○

To measure movement, the reference point must be

considered as nonmoving.

Multiple Choice

What is a reference point?

• A place or object that is staying still, that is used to determine if something else is moving.

• A place or spot where something is located

• The action of moving or being moved

• Shortest distance between starting position and ending position

Multiple Choice

What is your frame of reference if you are standing on the sidewalk and see the bus go by?

• the cloud in the sky

• the people in the bus

• sidewalk

• another moving car

Distance vs Displacement

Distance

• the total length of a path

• the total length from starting point to finishing point

• the value for distance can never be negative

• it is a scalar (just number no direction), for example 5m

Multiple Choice

• A

• B

• C

• D

Multiple Choice

You go on a hike on the blue path from point A to point B What distance did you travel

• 4.6 km

• 9.2 km

• 10.3 km

• 0 km

Displacement

• direct distance between two points

• can be negative or positive

• total distance determines how far the object has traveled from its original location

• it is a vector (with number and direction),for example 5m to the right

Check for Understanding

The rabbit is running from point
A to point B. The fox chases the
rabbit, and gets to a point where
it attempts to run around to
meet it at point B.

1. What is the distance the fox

travels?

2. Is the distance the same as

the displacement? Why or
why not?

Multiple Choice

What is the displacement the student traveled?

• A

• B

• C

• D

Multiple Choice

You go on a hike on the blue path from point A to point B. What is your displacement

• 4.6 km

• 9.2 km

• 10.3 km

• 0 km

Scalar vs Vector

• Scalar - a quantity, such as distance, that has magnitude (size) but does not take into account direction

• Vector - a quantity, such as displacement, that has both magnitude (size) and direction
