Displacement

By Grace Tang

You might be wondering: what the heck is the difference between displacement and distance?

Distance: How much you have moved in total.

Displacement: How much you have moved from your starting position.

Example:  You start a 0 meters. You moved forwards to 6 meters. Then you move back to 4 meters. Your displacement will be 4 meters because you will be 4 meters away from where you originally started. Your distance will be 10 meters because you have moved 10 meters total.

Blogging in Physical Science

Our blog can be used for a variety of purposes.  All physical science students can post extension work, reflections from our classwork, relevant website links, relevant videos, or any other content worth sharing to peers.  We encourage you to comment on other students work and engage in learning in a way that is meaningful to you.  The only rule of the blog is to be respectful and appropriate!

Force 5.2: Field Existence Independent of Interaction

Field  Existence Independent of Interaction

Summary: Fields are always present irrelevant to whether the object is interacting with another. Like when we sprinkled iron on top of a piece of paper that had a magnet underneath we could see the field was present before we stuck a paper clip to the magnetic.

Force 5.1 Field Strength and Force

Field Strength and Force

The stronger the field the greater is the force exerted on objects within that field. Irrelevant to what field we are talking about, the stronger the field is the more force it can apply on objects within it. For example, the bigger an object in space the bigger the gravitational field and it attracts objects at it at a much faster rate. Likewise the bigger the magnet the more magnetic objects it will pull at a larger distance.

The moon will pull you towards itself with a smaller force than the Earth

The bigger magnet will pull a nail towards it faster than the smaller one

Force as a Vector Quantity in Newtons

Summary: Forces a represented by a vector quantity that is a newton. A newton is the force required to push or pull a 1 kilogram object 1 m/s/s. This was discovered by Isaac Newton.
