NONE
2. the relationship between p and t is inverse and it is represented by the mathematical relationship position (time) = k
NONE
3. the relationship between v and t is constant and it is represented by the mathematical relationship velcoity=k
NONE
4. The relationship between p and t is parabolic and it is represented by the mathematical relationship position= k(time)^2
NONE
5. Define the term speed. Is it a vector or a scalar.
What is the change in distance over time? •What is a scalar?
6. 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
7. 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.
8. What is the distance covered between the 2nd and 6th second?
a 8m b 2m
c 6 m d 4m
• What is d:4m ?
• 6m-2m = 4m
9. What is a: Velocity ?
Velocity has direction in its measurement, circle motion must have a constant change in direction.
10. n
none
11. 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?
