Goals Understand forces as related to Newton’s 2nd Law Learn how to use free body diagrams Relate forces to kinematics
What are Forces? Forces give rise to acceleration The default unit of force is the Newton (N) The Newton is a 2 sec kg m g

Newton’s 2nd Law Newton’s 2nd Law appears as follows The summation of the forces gives rise to the acceleration The acceleration is NOT a force F ma Σ = r r
Free Body Diagrams Free body diagrams are an excellent way to keep track of

Unformatted text preview: all of the forces acting on an object First draw the object and then draw all the force Set the sum of the forces in a given direction equal to the mass times the acceleration in that direction Lets try an Example Kinematics and Forces After drawing a free body diagram we can find the acceleration by using Newton’s 2nd Law Once the acceleration is known the kinematic equations can be used to find unknown quantities Lets try some Examples Questions?...
