Integrated Fall Final Review

 Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

• 800

• 400

• 0

• 200

Bill runs 400 meters to Andy's house, turns around, and runs 400 meters back home.  What is Bill's distance?

• 0 meters
• 400 meters
• 800 meters
• 1600 meters

A person walks 50 meters directly north, stops, and then travels 32 meters directly south.  What is their displacement?

• 82 meters N

• 18 meters N

• 18 meters S

• 82 meters S

A place or object (like a stop sign or mailbox) used for comparison to determine if another object is in motion is called a

• comparison point

• frame of reference

• point of view

• motion detector

The unit for distance is:

• m
• s
• m/s

speed

• distance traveled per unit of time

• a change in the position of an object compared to another object (related term: move, movement)

• measured period during which something occurs

• a change in the velocity (speed, direction, or both) of a body (related word: accelerate)

velocity

• the speed and direction of moving objects

• distance traveled per unit of time

• a specific point in space

• a pull or push that is applied to an object

How can you tell if an object is in motion?

• the object will look different

• I'll be able to see the forces

• It will remain in the same position

• Its position will change in relation to other objects

Speed that remains the same or does not change

• Distance

• Constant Speed

• Mass

• Acceleration

What is velocity?

• The distance an object travels per unit of time.

• The change in position of an object.

• Speed in a given direction.

• The state in which one objects distance from another is changing.
