Transcript of netwon's law
Newton's first law of motion say that an object in motion will stay in motion and an object at rest will stay at rest unless acted on by an unbalanced force.
Newton's law of motion
An object will not change it's motion unless a force acts on it.
An object that is not in moving remains at rest until something pushes or pulls it
An object that is moving remains moving until something pushes or pulls it.
All objects resist having their motion changed.
This tendency to resist a change in motion is called inertia.
The more mass object has, the greater its inertia.
As the box gets pushed by the person behind it the box starts moving. The force he's putting on the box is pushing it because theirs no opposite force against him. The box might get harder to push as he pushes, because the frisson will slow down how fast he can push it. He is pushing straight across the ground. It's easier for him to push the box like that then pushing up a incline plane.
Their a chain on the roller coaster that takes it up the hill then at the top it gets released. The weight of the coaster basely pushes it down by its self. The coast goes up one side of the incline plane. It gets to the top and goes down the other side of the incline plane.
The second law of motion states that the force of an object is equal to its mass times its acceleration.
Newtons 2nd law of motion
A change in motion occurs only if a net force is exerted on an object.
A net force changes velocity of the object, and causes it to accelerate.
If an object is acted upon by a net force, the change in velocity will be in the direction of the net force.
The acceleration of an object depends on its mass.
The more mass an object has or the more inertia it has, the harder it is to accelerate
More mass means less acceleration if the force acting on the objects is the same.
Newton's third law of motion states that for every action there is an equal and opposite reaction.
When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object.
The force exerted by the first object is the action force.
The force exerted by the second object is the reaction force.
Newton's 3rd law of motion
If your mass is large then your acceleration will be slower then a smaller object. The car has a slower acceleration then the cap. It takes more force to get the car moving then it does to get the cap moving. The car could be faster just at the beginning the cars acceleration is slower.
It takes more force to move big rock then to move the little rock.The little rock has a small part on the table so it has less friction. The big rock has more area then the small rock so it has more friction as you pull. The kid has to put a lot of effort pulling the rock, if he had a pulley it would help him tremendously because, it would cut the effort in half. If he had the table at a incline it would be easier to pull it also.
As the rocket is taking of the thruster are pushing the
the rocket up in the air. The actions is the thrusters pushing off the ground and going up in the air. The rocket is the reaction because, its sitting there and getting pushed without having to do anything. It takes a lot of force to get the rocket up in the air. The action does a lot the reaction is just the outcome to the action.
The ball getting kicked is the action. The reaction
is the ball going in the air. The foot has the force to kick the ball up in the air. The ball has little to no resistant. so its easy to kick if you have the right footing.
