Newton's Law of Motion

How does Newton's Laws of Motion relate to this project? Post any issues you are running into so we can help.

Law 1: your unbalanced force that acts on the car is the mousetrap that makes your car move

Law 2: how much force it has depends on acceleration and mass

Law 3: action= mousetrap snapping
reaction= wood stops the trap

Newtons law is for every action there is an equal and opposite reaction. The action would be the mousetrap snapping and the reaction would be the axle spinning.

Newton also said that an object in motion stays in motion (if there is no resistance against it). Wheels with less traction on a mousetrap car cause less resistance, making the mousetrap car go a further distance.

law 1: when mousetrap pulls the wheel it will keep moving even when the mousetrap cannot pull any more

Newton's first law of motion is that an object will stay in its current state of motion unless another force acts upon it. The object is the car, and the outside force is the mousetrap that pulls the wheels forward. The second law is pretty much the same. The third law is that for every action there is an equal and opposite reaction. The action is the mousetrap snapping, and the reaction is the car moving forward.

Newton's Law:
For every action there is an equal and opposite reaction.

Mousetrap:
The mousetrap lever snaps back, which propels the mousetrap car forward.

The first law of motion is that every object in a state of motion stays in that state of motion unless an external force acts upon it. This relates to our project because the mousetrap car stays still until the mousetrap is snapped and pulls the string which, in turn, turns the back wheels of the mousetrap car. The string turning the wheels is the outside force that accelerates the car.

The second law of motion is that F=ma (force = mass * acceleration). The mass of the mousetrap car times the acceleration from the string turning the wheels becomes how much force the car has.

The third law of motion is that for every action, there is an equal and opposing action. For the mousetrap car, the opposing force that is going to stop it from going farther is going to be friction.

1-The car travels in a straight line until friction and gravity act on it

2-The force depends on speed and mass

3-The trap snaps,the back axle spins

One problem we have is friction in the back axle!!!

for every action there is an equal and opposite reaction. Action: the mouse trap snapping. reaction : the wheels moving

Newton's Law: For every action there is an equal and opposite reatcion.

The reaction is the lever of the mousetrap snapping and the reaction is the mousetrap car moving.

Newton's law is that for every action there is an equal and opposite reaction. The action in our mousetrap cars is the mousetrap snapping back, causing the reaction of the car moving. Also, he says that once in motion, an object will remain in motion until another force acts upon it. The force that causes the car to stop is friction. Thinner wheels usually have less friction, so they make the car go farther.

Newtons law states that an object will stay in motion until another force acts upon it. The wheels, which create friction against the floor, will slow the car down and eventually stop it

Neuton laws of motion is that for every action there is a reaction. The mouse trap snapping is the action the reaction is the wheels and axels spinning

amanda&lauren said...

Newton's law is that for every acton there is a reaction. The action is the mousetrap snapping and the reaction is the axel spinning.

Troy & Tyler said...

Newtons law says that for every action there is an equal reaction. The action is the mousetrap snapping and the reaction is the axle spinning and pushing the car forward.

The mousetrap car relates to newtons first law of motion because when it was stopped, all forces acting on it were balanced and therefore the net force was zero. The car didn’t go on forever (which also would’ve given it a net force of zero) but it eventually stopped because of air resistance and rolling friction.

The bar falls until it is stopped by the wood on the mousetrap. the mousetrap bar falling causes the wheels to turn.
