WARM UP: Get Out Homework Describe the difference between constant velocity and acceleration. Give a detailed example of each.
I Think I can, I think I can, I Think I can! - I can explain the relationship between acceleration, force, and mass. - So I can calculate the acceleration of different objects. - I am successful when I complete the “Newton’s Second Laws” handout.
force A force is a push or a pull An unbalanced force causes a CHANGE in motion, acceleration Measured in Newtons (N)
force When there is an unbalanced push or pull on something, it __________. All objects have ___________. ACCELERATES MASS
What happens to acceleration… When you apply a larger force what happens to the acceleration of an object? When you have a more massive object is it easier or harder to accelerate it?
How do we represent it in an equation?
So, how do we calculate Force? Force = mass x acceleration
Vector Has both Magnitude and Direction Represented by an arrow Force is a vector (amount)
Let’s sum it up Since direction is important vectors add differently. Head to Tail
MANIPULATING VECTORS ADDING 2 or more vectors can be added by placing them head-to-tail (dog-meets-dog method) and determining the RESULTANT vector. The RESULTANT vector is the vector you get when you add vectors; it goes from the very first tail to the very last head. RESOLVINGAny vector can be thought of a being made up of 2 perpendicular vectors. The 2 perpendicular vectors are called the COMPONENTS of the original vector
Net force: Balanced or Not? A box is being pushed by two stellar science students, one on each side of the box. Melissa is pushing the box with a force of 10 N to the left. Pedro is pushing the box with a force of 7 N to the right.
Net force: Balanced or Not? During tug of war Bri felt she was supergirl and attempted to beat Dylan. With one arm Bri applied 100 N force to the left. With two arms Dylan applied 100 N force to the right.
Think about it… During 4 th period Joanna was a beast. She resisted the forces applied by 5 people in her class all at once. Each person applied a force of 17 N and Joanna still did not move. How much force was she pushing back with?
Think about it… During 4 th period we put James in a box because he was talking too much. Since we could still hear him we decided to push him outside. The biggest force of friction from the ground on the box was a force of 68 N. If Mr. Kipp can apply a force of 25 N and every other student can apply a force of 6 N, how many students would we need to make the box start to move (accelerate)?
Let’s sum it up
