do you measure how far it will go and then time it
An anemometer is used to measure wind speed. A Pitot Tube is used to infer speed in an aeroplane,. A speedometer in an ordinary car, and a microwave or laser radar in a Police car.
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
Odos measure distance travelled, speedos measure speed at that moment.
speed.. distance..
The speed of a car is a measure of how fast it is moving over a certain distance in a specific amount of time. It indicates the rate at which the car is changing its position relative to a point of reference.
You can measure the speed of a remote control car by using a GPS speed tracker or an app on a smartphone. Simply attach the tracker to the car and drive it in a straight line to record its top speed. Alternatively, some remote control cars come with built-in speedometers that can provide real-time speed readings.
You could measure the time it takes the toy car to travel a known distance down the ramp. Then, you can calculate the speed by dividing the distance traveled by the time taken. Alternatively, you could use a speed-measuring device such as a radar gun to measure the toy car's speed as it moves down the ramp.
Speed... More specifically mph or kph
the speed is a unit of measure used to describe the rate of movement. As in the car went 35 mph while it drove down the street.
The speedometer of a car measures the speed at which the vehicle is traveling in miles per hour (mph) or kilometers per hour (kph). It provides the driver with real-time information about the vehicle's speed.
