200

When will displacement equal 0?

When object starts and ends at the same point

200

What is the equation used for calculating speed?

speed = distance / time

A sail boat is in the ocean. The current is moving 4 m/s east and the wind is blowing 7 m/s west. 

What is the resultant velocity of the boat?

3 m/s west

What does it mean if an object has a negative acceleration?

It is slowing down

300

How is it possible for 2 cars to travel the same speed but have different velocities?

they are traveling in different directions

400

Josh travels 10 km west, missed his destination, and walked back 3 km east.

What is Josh's displacement?

7 km west

400

How far can a car travel if it is going 50 km/h for 3.5 hours?

Distance = 50 km/h x 3.5 h

Distance = 175 km

A plane is flying at a speed of 600 km/h. 

How long will it take for the plane to travel 450 km?

T = 450 km / 600 km/h 

T = 0.75 h

500

What are the 2 scenarios that could occur and result in an acceleration = 0?

object is at rest

object's speed is constant
