Answer:

please mark as brilliant and give thanks

Explanation:

1. Measurement provides a standard for every day things and processes. From weight, temperature, length even time is a measurement and it does play a very important role in our lives. The money or currency we use is also a measurement. ... Thanks to these measurements present with us is the world is the same as we see today.

3. During projectile motion and where air resistance is negligible, momentum is conserved in the horizontal direction because horizontal forces are zero. Conservation of momentum applies only when the net external force is zero. The conservation of momentum principle is valid when considering systems of particles.

4. There are different types of motion: translational, rotational, periodic, and non periodic motion. A type of motion in which all parts of an object move the same distance in a given time is called translational motion. Examples are vehicles moving on a road, a child going down a bird flying in the sky.

5. Answer. Periodic motion : A motion which gets repeated after regular intervals of time is called a periodic motion. ... Non-periodic motion : The motion which does not repeat itself after regular interval of time is called non-periodic motion.

2. in order to measure the time in an athletics meet, stopwatches are used.
