Example: An Ice Skater connected to an Ice Sledge gains acceleration rapidly when pulled forward by it. If the force being applied is continuous, then the object decelerates at a faster rate, and if the force being applied is removed from the equation, then the object continues moving in the predetermined direction.
Examples: When a Footballer catches the Football before it hits the goal. This is an example of the moving football coming to an abrupt stop. If the force is applied to a resting object, the force itself determines the direction it is about to go in.
The angle can also be adjusted. If the force is applied to a moving object and in the same direction, then acceleration increases. If the force is applied to a moving object, not in the same trajectory, then greater force is required to change the route from the original direction. Also, acceleration varies with changes in direction. Example: In a game of cricket, when a Batsman receives a ball from the Bowler, the angle and acceleration with which the Batsmen hits the ball determines its direction and velocity.
The laws of motion we read in our curriculum are the fruits of hard-earned seeds sown decades before. The ease with which we utilize them now is because of the difficulties they had to grow through in finding them. Present-day scenarios for implementing these laws of force and motion have gained widened recognition, ranging from doorknobs to bicycles to pizza cutters. All these are practical witnesses to the theories. The world would not be what it is now without learning the use of force and motion for our benefit.

Changes in speed and direction contribute to the following results — Move a resting object. Increase or decrease the speed of an already moving object. Stop the motion of an already moving object. Types of Forces Since force has magnitude and direction, based on these, it is divided into two types — Contact Forces Non-Contact Forces 1. Contact Forces This type of force causes motion through contact, either directly or indirectly. Friction Force. F frict. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it.
There are at least two types of friction force - sliding and static friction. Thought it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion.
Friction results from the two surfaces being pressed together closely, causing intermolecular attractive forces between molecules of different surfaces.
As such, friction depends upon the nature of the two surfaces and upon the degree to which they are pressed together. The maximum amount of friction force that a surface can exert upon an object can be calculated using the formula below:.
F air. The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude and due to the fact that it is mathematically difficult to predict its value. It is most noticeable for objects that travel at high speeds e. F tens.
The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire. F spring. The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it. An object that compresses or stretches a spring is always acted upon by a force that restores the object to its rest or equilibrium position.
For most springs specifically, for those that are said to obey " Hooke's Law " , the magnitude of the force is directly proportional to the amount of stretch or compression of the spring.
Sanders' Site. Types of Forces Notes » Types of Forces. Forces A force is a push or pull acting upon an object as a result of its interaction with another object. My Resources. This force is caused by the table and is known as the normal force.
If you place a thin piece of wood or plastic a ruler works so that it is supported by both ends by books perhaps and place a small heavy object in the center, the piece of wood will bend. Of course it wants to straighten out so it exerts an upward force on the object.
This upward force is the normal force. You can feel the force yourself if you push down in the center of the piece of wood. The harder you push, the more the wood bends and the harder it pushes back.
Applied force refers to a force that is applied to an object such as when a person moves a piece of furniture across the room or pushes a button on the remote control. A force is applied. Frictional force is the force caused by two surfaces that come into contact with each other.
Friction can be helpful as in the friction that allows a person to walk across the ground without sliding or it can be destructive such as the friction of moving parts in a motor that rub together over long periods of time.
Tension force is the force applied to a cable or wire that is anchored on opposite ends to opposing walls or other objects. This causes a force that pulls equally in both directions. The spring force is the force created by a compressed or stretched spring. Depending upon how the spring is attached, it can pull or push in order to create a force.
Resisting force , like air resistance or friction, change motion. Whether the forces actually stop or slow something depends upon your point of view. Air friction makes a leaf travel along in the wind. When you pick up a pencil, it's friction with your fingers that gets the pencil in motion. In each case, the friction makes the two things like the air and the leaf move together.
Inertia is actually not a force at all, but rather a property that all things have due to the fact that they have mass.
