The speed of an object is equal to the distance traveled divided by the time taken to travel that distance. The faster an object is moving, the further it moves in the same amount of time.
Know MoreSpeed is a measure of how fast an object is moving. When considering the relationship between speed, distance and time, increasing the time taken for a journey decreases the overall speed. Decreasing the distance traveled increases the speed of an object if it takes the same amount of travel time. Speed can be measured in a number of different units, including meters per second and miles per hour.
The relationship between speed, distance and time provides the average speed of the journey. An object may have moved at that speed for the entire journey, or it could have traveled part of the journey faster and part of it slower.
To show how speed changes over time, rather than just calculating an average, a distance-time graph is used. This is a graph that plots how the distance traveled changes with time. The steeper the line of the graph, the faster the object is moving. If the graph line is horizontal, it means the object is stationary at that time.
Learn more about Motion & MechanicsSpeed is also known as velocity, and it is calculated by dividing the distance traveled by the amount of time it took to cover that distance. This is expressed as a standard equation: V = D / T.
Full Answer >The most common equation for speed is: speed = distance / time. It can also be expressed as the time derivative of the distance traveled. Mathematically, it can be written as v = s/t, or v = (ds/dt), where speed is denoted by v, distance is denoted by s, and time is denoted by t. In case of uniform velocity, the first equation is used.
Full Answer >The formula for speed is s = d/t, where s equals the speed, d is the distance covered and t is the time it took to cover the distance. The formula for finding the instantaneous speed at a specific point is found by taking the derivative of the speed equation.
Full Answer >Effort force is the force that moves an object over a distance by overcoming a resistance force. The formula for force is force = mass x acceleration or F = MA and is measured in newtons.
