Rest: An object is said to be at rest if it does not change its position with respect to its surroundings with time. Motion: An object is said to be in motion if the position changes with respect to it surrounding and time.
Are you at rest in a car?
You are at rest in reference to the car — since both of your have the same speed —; but you are moving in reference to the floor, people on the streets, buildings — since you and all of this elements have different speeds.
Are we at rest or in motion?
Rest and Motion are relative to each other. No body is at complete rest or in complete motion. Even when you are asleep , you are in motion w.r.t earth as earth is always in motion.
Are we always in motion?
You are correct: everything is in motion (or not) based on the reference frame . Motion is a relative concept, so you are never “moving” but only “moving with respect to something”.
Why is it safe to sit inside a car during a thunderstorm?
Cars are safe from lightning because of the metal cage surrounding the people inside the vehicle . This may sound counter-intuitive because metal is a good conductor of electricity, but the metal cage of a car directs the lightning charge around the vehicle occupants and safely into the ground.
Is a person in a moving car in motion?
If you see with respect to a person sitting inside the car you are at rest because your position with respect to him is not changing. But if you see it with respect to a person outside the car you are in motion because the respective positions are changing.
What are the 5 types of motion?
There are different types of motion: translational, rotational, periodic, and non periodic motion .
What keeps the universe in motion?
Everything in the Universe is in motion because forces exist in the Universe. The gravitational force and the electromagnetic force ensure large objects are in motion while the weak and strong nuclear forces ensure the quantum world is constantly in motion. If there were no forces, there would be no motion.
How you can keep your life in motion?
Walking briskly , taking the stairs, gardening, doing yard work and completing household chores are all simple activities that may make staying active an easier endeavor. Exercise and physical activity are good for all ages, including older adults.
Where is the safest place to be in a lightning storm?

Is a car safe during lightning?
Fact: Most cars are safe from lightning , but it is the metal roof and metal sides that protect you, NOT the rubber tires. ... When lightning strikes a vehicle, it goes through the metal frame into the ground. Don't lean on doors during a thunderstorm.
Is lightning hotter than the sun?
Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit ( 5 times hotter than the surface of the sun ).
Which best describes an object in motion?
You can describe the motion of an object by its position, speed, direction, and acceleration . An object is moving if its position relative to a fixed point is changing.
What is difference between speed and velocity?
The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement . Put another way, speed is a scalar value, while velocity is a vector.
How should we sit in a moving vehicle?
Your back should be pressed against the backrest, and your bottom should be as far back in your seat as possible. Avoid driving with your body scorched forward; if you can't reach the pedals or steering wheel, adjust your seat, not your body.
