Kinematics and SUVAT

A hummingbird averages a speed of about 45 km/hour (Cool facts: They visit up to 1000 flowers per day, and reach maximum speed, while diving, up to 160 km/hour!). Ruby-throated hummingbirds take a non-stop trip across Gulf of Mexico in which they fly for 18 hours straight! How far is the trip across the Gulf of Mexico at their average speed?

• 810 km
• 2.5 km
• 3.6 km
• 360 km

A car slows down from +32 m/s to +8 m/s in 4 s. The acceleration is 

• 6 m/s² opposite the motion

• 2 m/s² in the direction of motion

• 8 m/s² opposite the motion

What is the rate of acceleration of the object between 0 and 4 seconds?

• 1 m/s

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

Acceleration is defined as the CHANGE in 

• time of motion to another place. 
• velocity 
• distance 
• speed

• when the direction is straight

• when the velocity change is constant per unit time

• when the time is constant
