Instantaneous speed refers to the speed of an object at a specific point in time. Most speeds are average speeds, which is calculated by dividing the distance traveled by the time it took to travel it.Know More
The instantaneous speed of an object can only be calculated by dividing the distance covered by an object by the time it took during a very small time span. An accurate approximation can be obtained using a gauge or speedometer.
On a typical road trip that is 50 miles long and takes 1 hour to complete, the average speed of the car would be 50 miles per hour. Since speed usually changes at different points in a trip, the instantaneous speed may have been 55 miles per hour at one point and 45 miles per hour at another.Learn more about Motion & Mechanics
Instantaneous speed is an object's rate of motion at a particular time period or moment. Recording the speed of a running cheetah exactly 13 seconds after its sprint began would be an example of instantaneous speed.Full Answer >
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.Full Answer >
Speed measures how fast an object is moving, whereas acceleration is how much the speed of an object changes during a specified period of time. If an object is speeding up, it has a positive acceleration, whereas an object slowing down has a negative acceleration.Full Answer >
Velocity describes the speed and direction of an object. Speed tells how fast an object moves, but velocity is a vector measurement and includes both the rate and direction of an object's change of position.Full Answer >
