Newton’s Second Law. Newton’s second law of motion circular motion centripetal force. Lesson 3 Reading Guide - Vocab. How do forces change motion?. Forces change an object’s motion by changing its speed, its direction, or both its speed and its direction.

How do forces change motion?
How do forces change motion?(cont.)
When unbalanced forces act on a ball at rest, it moves in the direction of the net force.
Newton’s Second Law of Motion
According to Newton’s second law of motion, the acceleration of an object is equal to the net force acting on the object divided by the object’s mass.
You throw a 0.5 kg basketball with a force of 10N What is the acceleration?
Newton’s Second Law of Motion(cont.)
from Latin centripetus, means “toward the center”
Which term refers to speed in a certain direction?
Which refers to motion along a curved path?
Which refers to a change in velocity over time?
Do you agree or disagree?
5.When an object’s speed increases, the object accelerates.
6.If an object’s mass increases, its acceleration also increases if the net force acting on the object stays the same.
