An applied force is a force which is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.Return to Top
Gravity Force(also known as Weight)FgravThe force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity which is directed "downward" towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found by the equation:
Fgrav = m * gwhere g = 9.8 m/s2 (on Earth)
and m = mass (in kg)
(Caution: do not confuse weight with mass.)

Normal ForceFnormThe normal force is the support force exerted upon an object which is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. On occasions, a normal force is exerted horizontally between two objects which are in contact with each other. For instance, if a person leans against a wall, the wall pushes horizontally on the person.Return to Top
Friction ForceFfrictThe 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 cast, 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 which a surface can exert upon an object can be calculated using the formula below:
The friction force is discussed in more detail later on this page.Return to Top
Air Resistance ForceFairThe air resistance is a special type of frictional force which 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 which travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas. Air resistance will be discussed in more detail in Lesson 3.Return to Top
Tension ForceFtensThe tension force is the force which 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.Return to Top
Spring ForceFspringThe spring force is the force exerted by a compressed or stretched spring upon any object which is attached to it. An object which compresses or stretches a spring is always acted upon by a force which restores the object to its rest or equilibrium position. For most springs (specifically, for those which 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.

Which force causes acceleration?
The force that causes acceleration is known as net force.
How can one determine the friction force when given the mass and acceleration of an object?
To determine the friction force when given the mass and acceleration of an object, you can use the formula: friction force mass x acceleration. This formula helps calculate the force resisting the motion of the object due to friction.
How do you calculate the friction force when given the mass and acceleration of an object?
To calculate the friction force on an object, you can use the formula: Friction force mass x acceleration. This formula helps determine the force resisting the object's motion due to friction.
What is the relation between friction force and acceleration?
The friction force acting on an object is directly proportional to the object's acceleration. As acceleration increases, the friction force opposing the motion of the object also increases. This relationship is described by the equation F_friction = μ * N, where μ is the coefficient of friction and N is the normal force acting on the object.
What is an accelerating force?
An accelerating force is a force that causes an object to change its speed or direction of motion, resulting in acceleration. It can be exerted by various means, such as gravity, friction, or propulsion systems, and its magnitude is directly related to the object's acceleration according to Newton's second law of motion.
When will a force cause motion?
A force will cause motion, specifically it causes acceleration, whenever it is unbalanced by an opposing force, such as friction.
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

How does friction decrease the acceleration of a car?
friction decreases the acceleration of a car by creating a greater force which pushes against the acceleration force. the friction is a force, but more of it means that whatever is pushing against it ( acceleration in this case) is made smaller.
