Force and Acceleration
If you want to slow down or change the direction of the object, a force is required to do this.
-
When the motion of an object changes, the object is accelerating.
Newton’s second law of motion connects force, acceleration, and mass.
Acceleration occurs any time an object speeds up, slows down, or changes its direction of motion.
-
According to Newton’s second law, the net force on an object, its mass, and its acceleration are related by F(net)= ma
The force of the gravity between any two objects is always attractive and depends on the masses of the objects and the distance between them.
Force is measured in Newtons, abbreviated N.
In the equation, a is the acceleration, m is the mass, and F(net) is the net force.
To calculate a force in newtons from the equation shown on the prior page, the mass must be given in kg and the acceleration in m/s2.
