Four Forces

How many type of forces do you think there are?... Well there are four types of forces we use in our daily lives.😌🆒😱

-The first type of force is called the "Applied Force". This type of force is always some sort of push or pull. Which is caused by a person or thing. 
One example is when you push a cart at shaws. As you are pushing the cart you are applying force to it so it can move from it's place.👌

-The second type of force is called the "Gravitational Force". This type of force is usually a force that is attracting two objects. Usually one of the objects is earth! 
One example of this type of force is when you throw a ball to the ground the gravity doesn't let the ball stay on the ground. So it makes go up again. 

-The third type of force is called the "Normal Force". This type of force is usually a force from a surface. When usually the object is pushing up against gravity. 
One example of this type of force is  holding something on your hand. As you are holding the object on your hand the force of your hand is pushing up the force in the objects force. Which is a normal force because it's usually what happens daily. 

-The last type of force is called the "Tension Force". This type of force is a pulling force. Which is usually in a string,a rope,or chain. 
One example of this type of force is when you are pulling a car with a string. This is a tension force because your adding tension to the object by pulling it with a string. 

Now you know what is a force and the four different type of forces that exist. 😱🆒✅

Distance vs. Time Graphs

                



               How would you detect motion? Well in class we used motion detectors to try to match a graph on the monitor. What we did was that we connected the motion detector to a lap top, second we had someone stand in front of the monitor and they had to walk backwards and towards the detector. As the person was walking the detector was making a graph on the lap top. So when we had the graph we made we then had to match our graph with a graph that the detector already had. After we did the walking we had to record it on a lab we had in our notebooks and explain what movements we had to do so we could make the shape.


                I think these graphs are important in science because with these graphs you can tell if you are moving or not. So it is a good way to detect motion or to show motion. This is a good way to show motion to someone who isn't in the experiment with you.
