**Objective 1- Newton’s Three Laws of Motion**

AHSGE Standard VIII Objective 1- Newton’s Three Laws of Motion

2
Force The effort it takes to put an object of a certain mass into motion Force is the product of mass and acceleration Force is measured in Newtons Force needed to accelerate one kilogram of mass by one meter per second squared

3
Law of Inertia Newton’s First Law- An object in motion or at rest will remain the same unless acted on by a force. On Earth, there are two opposing forces to movement: gravity and friction! In space, there is no matter nor gravity (Vacuum). What do you think will happen if you throw a ball?

4
**Examples of the Law of Inertia:**

Example 1: The car is moving at a fast speed and stops abruptly, you lunge forward; the brakes stopped the car's inertia, not yours. That's what seat belts are for! Example 2: A penny is sitting on a piece of paper over a cup. The paper is quickly pulled out from under the penny and the penny falls. Gravity was free to act on the penny. Example 3: A fair ride is spinning to the right, but you get slung to the left. Your inertia is still trying to go straight, because the ride's inertia changes, but not yours.

6
Law of Acceleration Newton’s Second Law- An object will accelerate or decelerate in congruence with the force causing it. Unequal forces allow for movement or acceleration/deceleration. The greater the mass of an object, the greater the force required for movement or acceleration/deceleration Force = Mass x Acceleration

7
**Examples of the Law of Acceleration:**

Example 1: You push the gas pedal harder to go faster. Example 2: An object falls faster the closer it gets to the ground, because gravity is increasing the closer it gets to the ground. Example 3: The opposing forces from wind and the road will not let the car accelerate because the forces are equal.

**Density and Floating Bouyancy- The ability of an object to float**

The force of the water pushing up on the object is greater then the force of gravity pulling down Objects less dense than the fluids they are placed in will float Density = mass / volume Water’s density = 1 g/cm³ Objects with a density less than 1 g/cm³ will float

10
Law of Opposite Forces Newton’s Third Law- For every force their is an equal and opposite force. For every action, there is an equal and opposite reaction
