can someone tell me about the three laws of motion?

Question

pleez help me out i have homework but no book to do it with so i need to learn the 3 laws and i might need them to be explained

Answer 1

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. (Basically Galileo's law of inertia)

II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

III. For every action there is an equal and opposite reaction. (This law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction leaving us facedown in the water, if we aren't careful!)

Answer 2

OK, i did this last year. The laws of motion all deal with what will happen to a projectile object. For instance, if they collide they use the force that they used to collide with and go back that direction. Or imagine that you are on roller blades and beside you is a kart on wheels. The force you use to push on the kart gets transferred half to the kart and half to you, and should send you the same distance away from each other. Also, imagine you are in space, if you throw a banana you will go one way and the other way the banana go. Plus it will never get moldy if it ends up orbiting earth. Houston, we have a banana.
