“linear” quantities (distance s, speed v, tangential acceleration at) are related to the angular quantities (angle θ, angular speed ω, angular acceleration α) by a factor of r : s = r θ, v = r ω, a t = r α.
Vector form: r = r’ -r. Scalar form: s = s’ - s The total distance traveled by the particle, sT, is a positive scalar that represents the total length of the path over which the particle travels. The easiest way to study the motion of a particle is to graph position versus time. s. 0.
2-1 Position, Displacement, and Distance In describing an object’s motion, we should first talk about position – where is the object? A position is a vector because it has both a magnitude and a direction: it is some distance from a
To determine the displacement of an object, you only have to consider the change in position between the starting point and the ending point. The path followed from one point to the other does not matter.
Notice the subtle difference between these two ways. In the first approach, we have an approximate solution but the second one is exact. To get an exact distance in the first solution, we must determine the car’s accel-eration with all decimal digits! 3. An object uniformly accelerates at a rate of 1.00m/s2 east. While ac-
Answer: 1) 135 km, 85km forward 2) 0 m, 6 m • Distance ( ): the separation between two points. Ex, the length of an object. Usually measures in _____. No _____ needed ex) • Displacement ( or ): A measure of the change in position. Needs _____ Δd = final position – initial position.
Motion is a change in the location of an object, as measured by an observer. Distance, in physics terms, means the total length of the path travelled by an object in motion. The SI metric base unit for distance is the metre (m).
