    heavier one should fall two times faster than the lighter one. Galileo thought if a body is in freefall, their weight doesn 't determine speed but gravity does. He tested this by dropping objects from heights only to find out his theory wasn 't correct. He stated that the lighter object will go faster than the heavier object at first, but then the heavier body gains speed and arrives at the ground a few seconds before the lighter object does. This is another experiment that some argue Galileo…

    Gravity is always affecting you while swimming. Even you don’t think it is. Force of attraction by which terrestrial bodies fall toward the center of the earth. Newton’s first law of motion has a part to do with swimming. An object in motion stays in motion until another outside force takes place. Static Force & Dynamic Force is also motions that take place in swimming. (physics of swimming, Nov 12, 20104) Static Force takes place when you push off the wall or the bottom of the pool the drag…

    good speed by acceleration. To do this, my mousetrap arm and string have to exert enough force to get my car rolling. Lastly, Newton's third law applies to the performance of my vehicle as it explains the relationship of forces between the vehicle and the surface it must travel across. The wheels of the car push against the surface while the surface pushes back on the wheels which then allows the vehicle to push forward while friction acts in the opposite direction; gravity and normal force keep…

    is when external forces acting on a particle are balanced (zero resultant), the particle will be in equilibrium. But when external forces acting on a particle are not balanced, the particle will move in the direction of the resultant with magnitude ma. We use Newton’s second law to calculate the acceleration of a particle. Once the acceleration of a particle is known, we can apply equations of kinematics to obtain the…

    important. F=m(dv/dt)(Quote) F=ma Force = Mass x Acceleration (Newtons) With the use of this equation he proved that objects that are heavier fall at the same rate towards earth as objects that are lighter because the earth pulls them down with the same force. To put it in perspective a car and a feather would fall at the same universal rate of 9.8m/s^2 even though one is much heavier. Newton also figured out that the moon is held to the earth by the same force that pulls an apple off a tree…

    Propulsion is a force that pushes forward or drives and object forward. This concept can be seen in action with the use of a balloon powered car; this car demonstrates a type of propulsion system in which it produces thrust and potential energy and uses the kinetic energy that it will gain from the movement to push the car forward. The thrust is obtained from the balloon which applies Newton’s third of motion that states, “for every action, there is an equal and opposite reaction.” Specifically,…

    Newton’s First Law, which states, “An object in motion stays in motion unless acted upon by an unbalanced force” they make a pass and it is collecting water because it is raining outside and the more water it gets filled up with the more weight and mass/pressure is being put towards the ball think of it as the Toy cart \experiment the more mass it was put on the less it accelerate but with the force it gets from falling down the ramp is like the soccer ball the water is the mass/weight that is…

    arrow is a major factor in the flight of the arrow, the center of mass needs to be towards the front of the arrow so that the distance that the arrow flies will increase. The further the center of mass is away from the center of drag will decrease speed but make the arrow fly better. A bow provides an arrow with momentum, where momentum is defined as mass x velocity. Another key thing involved the arrow is its stiffness or spine, the arrow needs to be able to bend around the bow when it is…

    1. How do you adjust the pulling force of the mousetrap? Adjusting the length of the snapper will change the pulling force—making something move as it goes in a certain direction. Making the snapper on the mousetrap longer will decrease the pulling force and a shorter snapper will increase it.…

    the difference between motion and forces? Are there different types of motions and forces? What is gravity? What is Newtons law? Does friction have to do with motion or force? Does Newton's law apply to everything that is moving? How is movement and forces apply to the world itself? Do natural disasters involve motion and forces? Does energy have to do with motion and forces? How many types of forces are there? How does the earth create forces? Is an earthquake involve…
