Establishing Relationships and S and V

 The relationship between p and t is direct and it is represented by the mathematical relationship position=k(time) NONE the relationship between p and t is inverse and it is represented by the mathematical relationship position (time) = k NONE the relationship between v and t is constant and it is represented by the mathematical relationship velcoity=k NONE The relationship between p and t is parabolic and it is represented by the mathematical relationship position= k(time)^2 NONE 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 ? 6m-2m = 4m What is a: Velocity ? Velocity has direction in its measurement, circle motion must have a constant change in direction. n none 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?
