Transcript of Newtons
Newton's Third Law
states that for each action there is an equal and opposite reaction.
Newton's First Law
says that an object in motion/moving will stay in motion. Also that an object at rest will stay at rest unless acted on by an unbalanced force.
Newton's Second Law
states that the force of any object is equal to its mass multiplied by its
The cars in the images on slide 3 are showing Newton's first law. Unless the person is making the car move by applying pressure to the gas it won't move but if you don't apply pressure to the brake the car won't stop either. Also if the car isn't moving unless you apply force by either pushing the car or pressing the gas the car will not move. It has to have force to move.
The small baseball is going to take less acceleration to get it to move to point B then the much heavier bowling ball. This is because the mass of each is different and heavier objects require more acceleration in order to move them. If I try to move the bowling ball using the same amount of acceleration that it takes to move the baseball it isn't going to move the bowling ball much at all.
The hammer and nail are acting against one another. The hammer puts force against the nail and presses it down but without the nail the hammer wouldn't be receiving its force either. The vibrations that the nail sends out when hit by the hammer makes the hammer more powerful. The two of them work together and without the other. The bond would be useless.
