The diagram below shows a 5.0-kilogram bucket of water being swung in a horizontal circle of 0.70-me-ter radius at a constant speed of 2.0 meters per second. Any moving object has a position that can be considered a function of time. When the motion is along a straight line, the position is given by a single variable, which we denote by \(s(t)\text{.}\) For example, \(s(t)\) might give the mile marker of a car traveling on a straight highway at time \(t\) in hours. Sound moves through the air at a speed of around 343 meters per second, which is 1234.8 km/h or 767 mph (at 20 °C / 68 °F). It means that a sound wave in air needs about 2.9 seconds to travel one kilometer, or 4.7 seconds to travel a mile - this data might be useful for storm-hunters to determine the lighting distance .

The equation. When an object moves in a straight line with a constant acceleration, you can calculate its acceleration if you ... “Every object continues in a state of rest or in a state of motion in a straight line at constant speed, unless it is compelled to change that state by forces exerted on it” Simply stated, the motion remains unchanged unless there is a force present. At 1.0 s it is back at the origin where it started. The particle’s velocity at 1.0 s in (b) is negative, because it is traveling in the negative direction. But in (c), however, its speed is positive and remains positive throughout the travel time. We can also interpret velocity as the slope of the position-versus-time graph. the objects path. 14. 15.
