What are Forces?

What are Forces?

What are Forces? Module 3 What are forces? In module 2 we learned that a force is a push or a pull. We learned that Newton’s 2 nd Law states that a Force is equal to the mass of a moving object times its acceleration.

Conservation of Mechanical Energy

Conservation of Mechanical Energy

Conservation of Mechanical Energy. 6.5. Mechanical Energy. KE and PE = total mechanical energy E = KE + PE Actually there are other forms of energy to include, but we haven’t met them yet in the book. Work Energy Theorem (again). W nc = (KE f – KE 0 ) + (PE f – PE 0 ) Rearrange

Projectile Motion

Projectile Motion

Projectile Motion. Concerns the flight of an object or body after it is free of support. (This includes objects that are dropped.) The flight path of a projectile is called the trajectory. Objects that are continuously being propelled (such as airplanes) aren’t considered projectiles.

Explaining Motion Revision

Explaining Motion Revision

Explaining Motion Revision. Forces. Forces arise from an interaction between 2 objects. In an interaction pair the forces are equal in size but opposite in direction. These forces act on different objects. They explain how rockets work etc. Forces (cont.).

Free-Fall Motion

Free-Fall Motion

Free-Fall Motion. By: Robert McGee. What happens ?. 1) When you drop a rock from a cliff? Ans: It falls downward. 2) When a Skydiver jumps from a plane? Ans: He/She will fall to the ground. 3) To a skydiver’s speed as he is falling?
