Question

3 commonly used gadgets on newtons 1 law of motion

Answer 1

1. Roller coaster: A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. This combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coastermoves up, down, and around the track.

2. sand clock: Uses Newton’s gravity.

3. space craft: For launching it is based on the 3rd law of motion. In space for providing thrust, in the absence of gravity, they give using First law of motion.
