Define the term speed. Is it a vector or a scalar.
What is the change in distance over time? •What is a scalar?

An object moves a distance of 10 m in 5 seconds. The average speed of the object is
a. 0.5 m/s c. 40 m/s
b. 2.0 m/s d. 50 m/s
 What is answer b. 2.0 m/s?
 V= d/t =10m / 5s = 2.0 m/s

As a cart travels around a horizontal circular track, the cart MUST undergo a change in
a:velocity b:speed
c:inertia d:weight
 What is a:Velocity ?
 Velocity has direction in its measurement, circle motion must have a constant change in direction.

What is the distance covered between the 2nd and 6th second?
a 8m b 2m
c 6 m d 4m
 What is d:4m ?
 6m2m = 4m

What is a: Velocity ?
Velocity has direction in its measurement, circle motion must have a constant change in direction.


The average speed of a plane was 600 kilometers per hour. How long did it take the plane to travel 120 km?
a:0.2 h b:0.5 h
c:0.7 h d:5 h
 What is a : 0.2 h ?
 v = d / t
 600 km /h = 120 km / t
 t = 120 km / 600 km / h
 t = . 2 h?
