Newton’s First Law:

• Newton’s first law also commonly known as the law of Inertia, which states that objects tend do what they are already doing (staying still, stays still or going at a speed will not change speeds suddenly), if there are no unbalanced forces acting on the object. One way to measure Inertia is to find gravitational mass which is numerically equal to inertial mass, so the greater the gravitational mass the greater amount of inertia.
• In this video the soccer ball is already still so relating to the law it wants to stay still because it was already doing that (and thats why it doesn’t move).
• Some things that can be taken into consideration would be the texture/shape of the ball as it could hold it easier with a square then a sphere, or that there is no wind to move it, so other conditions would effect it sometimes, so you just have to be aware (for example if you were to hit a patch of black ice just because you were going forward doesn’t mean that you will continue to go that way although your car may want to the tires friction would be lost and your inertia would go down

Newton’s Second Law:

• The main noted point of newtons second law is that if unbalanced forces act on an object that object will accelerate, and depending on the unbalanced force and the mass of the object we can determine the acceleration.
• With the unbalanced force being the applied force you can see that the care starts to accelerate.
• Some things that could affect this would be the air resistance or force of friction although your object might be accelerating it could also slow because of the friction being exerted on it.

Newton’s Third Law:

• The third law the main point can be summed up for the fact that for every action there is an equal and opposite reaction.
• The wheels on the scooter are using an action reaction force to move it, the wheels are rotating forward while the ground is pushing against it causing to move. Since I didn’t push that hard she didn’t go that far, but if I did push hard she would have gone way further because the force on her must be the same that I was putting in to push it in the first place.
• Some contradictions you might find surrounding the law is that if you were to say punch a wall hard then the wall would break even though it shouldn’t if it reacted like it would be predicted then you wouldn’t be able to break through because it would just exert the force back into your hand. Newtons third law can also be commonly compared to when your riding your bike or even going for a jog, but for it to make a lot more sense just think of it like a trampoline.
