3 A push or pull The rate at which something moves in a certain amount of time Increase in speed of something Both Speed and Direction (Vector shows direction and Magnitude) Tendency to do nothing or remain unchanged When unequal forces cause objects to move When two equal forces act on an object Resistance to motion when another object moves across that surface Amount of energy transferred by a force

4 Born Dec 25th 1642 Died March 31 st 1727 Developed “Laws of Motion” Mathematically defined “Gravity” Autistic, Brilliant Mathematician, Mason F=ma Force= Mass times Acceleration Acceleration is produced when an unbalanced force acts on a mass The greater the mass, the greater the force is required to move to accelerate the object An object at rest stays at rest until acted on by an unbalanced external force An object at in motion stays in motion until acted on by an unbalanced external force For every action there is and equal and opposite reaction

5 Book sitting on shelf Someone flying through windshield when car stops suddenly Leaning to side in tight turn in cornering car Inertia is a property of all matter Tendency to remain unchanged (Balanced forces) Force resisting the relative motion of solid surfaces over one another

6 Force equals mass times acceleration F=ma so,...42kg x 25 m/s= 10.5 N F=ma so,….. 5 divided into 20 Acceleration =4m/s F=ma so,… F= 300kg x4 m/s 2 F= 1200 N

7 Rocket’ thrust expels atoms in one direction creating unbalanced forces, and the rockets' atoms move in the opposite direction When you create unbalanced forces by pushing on the atoms in the wall, you are repelled in the opposite direction and move away from the wall. When I let go of the balloon, the unbalanced forces would move air in one direction, and the balloon’s mass in the opposite direction

10 Constant speed (Never changes speed) Object not moving (Time is changing, but distance is not) Object turns around and heads back to start location Object is accelerating and getting faster!
