Newton's 1st Law of Motion | Physics - Forces & Newton's Laws
In this video we'll learn about net force, balanced and unbalanced forces, Newton's 1st Law of Motion and how to explain different examples of motion using Newton's first law.
Newton's 1st law: An object at rest will remain at rest and an object in motion will continue moving in a straight line at a constant speed unless acted on by a net force.

This video will introduce dynamics (vs kinematics) and we'll start to talk about Newton's laws of motion and why objects move in different ways. We'll cover what forces are and how we draw them as vectors with a magnitude and direction. Then we'll introduce the different types of forces that we'll learn about in the course: applied force, normal force, friction force, tension force, spring forc...

    I still don't understand why we always use (-g) whether the object is going up or down

    • @physicslab42
      @physicslab42 6 днів тому

      Yeah that's a common point of confusion. The acceleration of g (9.8 m/s²) is caused by gravity, which always acts downwards no matter what's happening, gravity and the acceleration never act upwards. So even if an object is moving up (it's velocity is up) the acceleration is still down. That has the effect of slowing down the speed of an object moving up, and speeding up an object if it's moving down. Does that help or still confused?

      @physicslab42 Місяць тому

      Yup if you are writing a number in scientific notation you would move the decimal until there is one digit to the left of it. The number of places you moved the decimal is the exponent above the 10 (the exponent is positive if you moved the decimal left and negative if you moved it right).

  • @mrigyank_
    @mrigyank_ 2 місяці тому

    i understand why we use a tangential line to describe the linear velocity's direction but why cant we use the same for displacement?? why is linear displacement's direction described as the arc of the circular track and not the tangent because the direction of velocity vector should be same as displacement right?

    • @physicslab42
      @physicslab42 2 місяці тому

      That's a great question! I'm not sure if I have a good answer for you, some of it just comes down to the words we use to describe different things. The word "displacement" by itself already has a definition, which is the straight line distance between a start and end point. For example if a car drove 1/4 of the way around a circle, it's "displacement" is the straight line distance between the two points and I use the words "tangential displacement" to describe the arc length of the car's path. I could have just used "arc length" or "distance" instead, but I used "tangential displacement" because displacement is a vector which can be positive or negative, and we need to include whether that arc length is positive or negative based on the axis we set up. For an object in circular motion the "tangential displacement" will always be an arc length that curves around a circle, so it can't be along a straight line tangent to the circle. If an object was moving in a straight line then the displacement would be in the same direction as the velocity. But for an object in circular motion the direction of the tangential velocity is constantly changing, so the displacement is not in the same straight line direction as the velocity (there is no single direction of the velocity). I can see how this stuff can be confusing, hopefully that helps a little bit!
