Inertia NEWTONS FIRST LAW OF MOTION 5 2017 The Institute for the Professional Development of Adult Educators An object at rest stays at rest and an object in Newtons First Law motion stays in motion with the same speed and in the same direction unless acted upon by an

unbalanced force. 6 2017 The Institute for the Professional Development of Adult Educators Newtons First Law Inertia A property of matter by which it continues in its existing state of

rest or uniform motion in a straight line . . . 7 2017 The Institute for the Professional Development of Adult Educators Newtons First Law . . . Unless that state is changed by an external force.

8 2017 The Institute for the Professional Development of Adult Educators Newtons First Law Balanced vs. Unbalanced Forces 9

If the forces on an object are equal and opposite, they are said to be balanced. If they are not equal and opposite, then the forces are unbalanced and the motion of the object changes. 2017 The Institute for the Professional Development of Adult Educators

full of dishes Lawn bowling on a cut and rolled lawn versus an uncut lawn When riding a horse, the horse suddenly stops and you fly over its head In a plane taking off, you feel pushed back into your seat 12 2017 The Institute for the Professional Development of Adult Educators Newtons First Law

Force and Acceleration NEWTONS SECOND LAW OF MOTION 14 2017 The Institute for the Professional Development of Adult Educators Newtons Second Law The relationship between an objects mass m, its acceleration a, and the

applied force F is F = ma An unbalanced force acting on an object causes it to accelerate. The more force you apply, the quicker something accelerates. 15 2017 The Institute for the Professional Development of Adult Educators Newtons Second Law

Force a push or pull that causes an object to move, stop, or change direction Mass the amount of matter in an object Acceleration the rate at which

an objects velocity changes over time F = ma 16 2017 The Institute for the Professional Development of Adult Educators Newtons Second Law 17

2017 The Institute for the Professional Development of Adult Educators Newtons Second Law 18 2017 The Institute for the Professional Development of Adult Educators Newtons Second Law Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's

Second Law, you can compute how much force Mike is applying to the car. 0 5 : r e s w n s o

Newtons Second Law A sports utility vehicle has lower gas mileage than a standard car Hitting a golf ball with different levels of force changes the balls direction and distance Catching a ball and swing your hand back to provide the ball time to lose its speed A 12 lb. bowling ball goes down the lane faster than a 15 pound bowling ball Its easier to push an empty shopping cart than a full one 21

ewton-s-Second-Law 22 2017 The Institute for the Professional Development of Adult Educators Action and Reaction NEWTONS THIRD LAW OF MOTION Newtons Third Law For every action ,

there is an equal and opposite reaction. 24 2017 The Institute for the Professional Development of Adult Educators Newtons Third Law Why does it hurt so much when you stub your toe? When your toe exerts a

force on a rock, the rock exerts an equal force back on your toe. The harder you hit your toe against it, the more force the rock exerts back on your toe (and the more your toe hurts). Newtons Third Law Force Pairs - Action & Reaction 26

Examples Newtons Third Law Birds flying through the air (wings push down and air pushes them up to provide lift) Walking (your feet push down and the floor pushes up) When you push on a door and it pushes back with equal and opposite force Air rushing out of balloon A fish swimming (uses fins to push water backwards and therefore propels itself forwards) A plane flying (four major forces lift, weight, thrust, drag) Diving off of a diving board
