Velocity Speed and Motion Oh My Velocity and speed are very similar ideas but velocity is a vector and speed is not.Suppose we knew that someone was driving at thirty-five kilometers an hour (35 kmhr) but the direction wasnt given.As mentioned earlier in Lesson 1 an object moving in uniform circular motion is moving in a circle with a uniform or constant speed.The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion many students have the misconception that there is no acceleration.

The Meaning of Constant Acceleration. Sometimes an accelerating object will change its velocity by the same amount each second. As mentioned in the previous paragraph the data table above show an object changing its velocity by 10 ms in each consecutive second.Explore the forces at work when pulling against a cart and pushing a refrigerator crate or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion In physics uniform circular motion describes the motion of a body traversing a circular path at constant speed.Since the body describes circular motion its distance from the axis of rotation remains constant at all times. Though the bodys speed is constant its velocity is not constant velocity a vector quangraphicy depends on both the bodys speed and its direction of travel.

Both addition and subtraction with vectors follows the same algebraic rules as with real numbers. The commutative rule u v v u The graphicociative rule u (v w) (u v) w The fancy terminology and symbols aside this is really quite a simple concept.Acceleration is by definition the time rate of change of the velocity.While speed is a scalar velocity is a vector velocity has magnitude and direction. (See the module on constant acceleration and the page on vectors.)In the animation below the velocity vector is shown as an arrow.In physics a force is any interaction that when unopposed will change the motion of an object. A force can cause an object with mgraphic to change its velocity (which includes to begin moving from a state of rest) i.e. to accelerate.Force can also be described intuitively as a push or a pull. A force has both magnitude and direction making it a vector quangraphicy. ## Motion In And Dimension
