Answer 1

Answer:

Uniform motion.

A body is said to be in uniform motion if it travels equal distances in equal intervals of time, no matter how small these time intervals may be.

Non - uniform motion.

A body is said to be in a non-uniform motion if it travels unequal distances in equal intervals of time.

Fast motion.

action that appears to move faster than normal on the screen, accomplished by filming the action at less than normal speed in the camera and then projecting it at normal speed.

can we compare the types of motion ofobjects from their speeds?

Answer. 2. if the body is moving in uniform speed in equal interval of time then it is called as a uniform motion. ... if body is moving non uniformly in equal interval of time then it is called as a non uniform motion

What is the function of a speedometer?Where is it used?

A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards.

is the standard unit for themeasurement of speed?

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.
