   How does force affect motion?

   • Forces by an object only affect the motions of the other objects that they act on. The amount of net force on an object is proportional to the amount of acceleration it experiences, and the constant of proportionality is the mass, a measure of how much stuff is present in the object. (Newton’s second Law)

   What causes acceleration?

   • Forces are the cause of accelerations. It is impossible to have one of these without the other. This means that forces (if the vectors don't all cancel each other out) speed up, slow down, or change the direction of an object’s motion.

   Is force related to velocity?

   • We know that force is related not to velocity (because the first law says that constant velocity exists in the absence of force), but rather the change of velocity. More specifically, the rate of change of the velocity – the acceleration. Newton defined force in the simplest possible fashion in terms of acceleration – with a linear relationship.

   Does acceleration increase or decrease if mass increases?

   • In other words, the acceleration of an object increases if the resultant force on it increases, and decreases if the mass of the object increases. The ratio of force over acceleration is called inertial mass close inertial massA measure of how difficult it is to change the velocity of an object.

   What is a force causing a mass to accelerate?

   • a situation in which the only force acting on an object is the force due to gravity external force a force acting on an object or system that originates outside of the object or system net external force the vector sum of all external forces acting on an object or system; causes a mass to accelerate free-body diagram

   Is acceleration directly proportional to external force?

   • Now, it seems reasonable that acceleration should be directly proportional to and in the same direction as the net (total) external force acting on a system. This assumption has been verified experimentally and is illustrated in Figure \(\PageIndex{1}\).

   Acceleration significantly changes the nature of an object’s motion by altering its velocity over time. This change can happen in three primary ways: Ways acceleration affect motion. Increasing speed. Decreasing speed. Changing direction. Let’s explore each of these effects in more detail: Increasing Speed.

    Acceleration is directly proportional to the force exerted on the object. It is important to consider to what extent the results show this relationship.
