The concept of force refers to a push or pull that can cause an object to accelerate or change its motion. It is described by its magnitude, direction, and point of application.
There are several types of forces, such as contact forces (like friction and air resistance) and non-contact forces (like gravity and magnetic force). Other types include tension, compression, and normal force.
The net force on an object is the sum of all forces acting on it. To calculate it, you need to determine the magnitude and direction of each force and then add them together vectorially.
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed as F=ma, where F is force, m is mass, and a is acceleration.
To calculate force from acceleration and mass, you can use the formula F=ma. Simply plug in the known values for acceleration and mass to determine the force acting on the object.
