The relationship between force and acceleration is described by Newton's second law of motion, which states that the net force applied to an object is directly proportional to its acceleration. This relationship can be mathematically represented by the equation F=ma, where F is the force applied, m is the mass of the object, and a is the resulting acceleration.
Force is measured using a unit called the Newton (N). One Newton is equal to the amount of force needed to accelerate a mass of one kilogram by one meter per second squared.
The acceleration of an object is affected by two main factors: force and mass. The larger the force applied, the greater the acceleration. Similarly, the larger the mass of the object, the smaller the acceleration will be for a given force.
No, according to Newton's first law of motion, an object will remain at rest or in motion with a constant velocity unless acted upon by an external force. In other words, an object cannot have acceleration without a force acting on it.
The direction of the force applied to an object will determine the direction of its resulting acceleration. For example, if a force is applied in the same direction as an object's motion, it will increase the object's speed. If the force is applied in the opposite direction, it will decrease the object's speed.
