Be careful when discussing the writing assignment speed velocity and acceleration direction of the acceleration of an object; slow down, apply some thought and use the rule of thumb. For more information on physical descriptions of motion, visit. The Physics Classroom Tutorial.Detailed information is available there on the following topics: Vectors and Scalars, speed and Velocity, acceleration. Describing Motion with Vector Diagrams, motion Along Inclined Planes. The Physics Classroom the Calculator Pad, overview, problem Set, audio Guided Solutions 1-D Kinematics: Problem Set Overview.This set of 35 problems targets your ability to use the average velocity and average acceleration equations, to interpret position-time and velocity-time graphs, and to use the kinematic equations to determine the answer to problems, including those which involve a free fall acceleration. Problems range in difficulty from the very easy and straight-forward to the very difficult and complex. The more difficult problems are color-coded as blue problems.
And a car moving westward would be described as having a westward velocity. The direction of the acceleration vector is not writing essay advantages disadvantages so easily determined.As shown in the animation, an eastward heading car can have a westward directed acceleration vector. And a westward heading car can have an eastward directed acceleration vector. So how can the direction of the acceleration vector be determined?A simple rule of thumb for determining the direction of the acceleration is that an object which is slowing down will have an acceleration directed in the direction opposite of its motion. Applying this rule of thumb would lead us to conclude that an eastward heading car can have a westward directed acceleration vector if the car is slowing down.
Accelerating objects have a changing velocity - either due to a speed change (speeding up or slowing down) or a direction change. This simple animation above depicts some additional information about the a good essay writing website car's motion. The velocity and acceleration of the car are depicted by vector arrows.The direction of these arrows are representative of the direction of the velocity and acceleration vectors. Note that the velocity vector is always directed in the same direction which the car is moving. A car moving eastward would be described as having an eastward velocity.
The Physics Classroom multimedia Studios » 1-Dimensional Kinematics » Hot Wheels Track, consider the motion of a Hot Wheels car down an incline, across a level and straight section of track, around a 180-degree curve, and finally along a final straight section of track. Such a motion is depicted in the animation below.The car gains speed while moving down the incline - that is, it accelerates. Along the straight sections of track, the car slows down slightly (due to air resistance forces).Again the car could essay writing learning outcomes be described as having an acceleration. Finally, along the 180-degree curve, the car is changing its direction; once more the car is said to have an acceleration due to the change in the direction.
