Forces
Contact
Twist
A twist force is to alter an object into one which is in the form of a distorted shape. The object can be bent, twisted and altered into an object that looks completely different to the original one
Some facts about a twist force is that when you do a twist or a turn on a skateboard, Friction slows down movement when two objects rub against each other. This is what lets you do tricks and flips on a skateboard.
-
Normal
An example of a normal force is when a tennis ball falls down a slope and moves. This is a normal force because the ball is placed on top of the book and then rolls down the slope/book and is rolling down the slope
A normal force is the support force which is exerted upon an object that has come in contact with another object.
-
Pull
A pull force means to pull something towards you with the force of pulling. A pull force usually cannot change the shape of an object but like a push force. This may also change the speed of an object.
Some characteristics of a pull force will be the state of motion that the object is in and the position of the item that is being moved.
I don't know if this counts as a non contact force but when you suck water through a straw, you are not touching the water until it reaches you're mouth so that might count as a pull force being a non contact force.
Friction
A friction force is when two objects rub together it creates friction. Friction may create static electricity which can make hair stand up on head (See example). Friction can vary depending on what you are rubbing together.
An example of friction is when you rub the balloon on your head which creates static electricity and makes the hair on your hair stand up. This happens because the static electricity created from the friction between the hair and the balloon is attracted to the hair making the hair stand up
Some characteristics of friction include moving the one of the objects depending on what the friction is between the two objects.
-
Push
A push force is when you push the item in the forwards direction, creating a push force. When an object is pushed, it may change its shape, position or speed depending on what object you're pushing and where you push it.
The example for the push force could be pushing the ball of Plasticine down and changing its shape which is another characteristic of the push force.
The factors that go towards how far the ball goes when hit by a bat include how hard you hit it because the harder you hit it, the more force is put onto the ball. Another factor is the angle you hit it on because if you hit it straight up, it will just come straight down without going anywhere, but if you hit it forwards on a 45 degree angle for arguments sake, It will go a fair distance again depending on how hard you hit it.
Some characteristics of a push force may include changing the direction of an object by pushing it in a certain direction, changing the shape of the object by pushing it against another solid object to squish the object depending on the consistency of the object and change the speed by pushing it down a certain slope of at a particular speed
Non Contact
Magnetic
A magnetic force is the attraction of two objects (examples may include magnets etc.). These objects are attracted to each other for different reasons but the main one is to do with friction.
-
An example of a magnetic force is was when the paper clip became attracted to the magnet and moved towards the magnet. This showed a magnetic force because the magnet was becoming attracted to the paper clip making it move closer to it
Some characteristics of a magnetic force are that they seek the path of the shortest distance to get to the other attractive object.
Electrostatic
An electrostatic force is a non contact force which is when two objects are attracted to each other creating a pull force between them
An example of an electrostatic force is the balloon and the hair trick. I know I used this before but it falls under the same category in the sense that friction creates electrostatic electricity.
Some characteristics of electrostatic forces including the fact it can either be repulsive or attractive (Like a magnet or battery).
-
Gravity
Gravity is a non contact force that draws objects towards the center of the earth. In space there is no gravity as there is no atmosphere but one earth there is, making any solid object fall.
-
An example of a gravity force is when we dropped the ball and it fell to the ground (Getting pulled towards the center of the earth).
Some characteristics of gravity include a pull force because gravity means for everything to be moved to the center of the earth which means the object is being pulled by gravity towards the center of the earth.
-
-
An example of a pull force is when you pull an object along the ground. This is a pulling force because you are pulling a object towards yourself making it a pull force.
