velocity related to the force you apply? Or does the force just change the velocity? Also‚ what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one. A Force Sensor and an Accelerometer will let you measure the force on a cart simultaneously with the cart’s acceleration. The total mass of the cart is easy to vary by adding masses. Using these tools‚ you can determine how the net force on the cart‚ its

influence of significant gravitational forces? _______ Explain your answer. 5. If a moose were chasing you through the woods‚ its enormous mass would be very threatening. But if you zigzagged‚ then its great mass would be to your advantage. Explain why. 6. Inertia can best be described as _____. a. the force which keeps moving objects moving an stationary objects at rest. b. the willingness of an object to eventually lose its motion c. the force which causes all objects to stop d.

reaction. The Introduction in every interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs. A variety of action-reaction force pairs are evident in nature. Consider the propulsion of a fish through

Conservative force - Any force which conserves mechanical energy‚ as opposed to a nonconservative force. See statement of conservation of mechanical energy. Conservative System - A system in which energy is conserved. Energy - The ability to do work. Kinetic Energy - The energy of motion. Nonconservative Force - Any force which does not conserve mechanical energy‚ as opposed to a conservative force. Path independence - Property of conservative forces which states that the work done

interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Interaction between the hammer and nail A hammer exerts a force on the nail and drives it into a board . But this is not the only force present for there must also be a force exerted on the hammer to stop it in the process. What exerts this force? The nail does. Newton reasoned that while the hammer exerts a force on the nail ‚ the nail

The Ramp (and Friction) PhET Simulation Lab go to: phet.colorado.edu/en/simulation/ramp-forces-and-motion Introduction: When an object is dragged across a surface‚ the force of friction that must be overcome depends on the normal force as F=uN and the normal force is given by N= Wy‚ the vertical component of weight pointing perpendicular to the surface. When the angle of an inclined plane changes‚ the normal force changes and so does the friction. In this lab‚ you will change the angle of an inclined

There are two ways that this question will be answered. First‚ through the basic principles and then through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill‚ gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the

objects at rest will stay at rest unless and unbalanced force acts on it. One aspect of a car that relates to Newton’s first law is how if a car a car will continue doing what its doing unless an unbalanced force is applied. For example a car parked in a driveway will not drive forward or reverse unless an unbalanced force is applied. When in motion a car travelling at 50m/s will continue travelling at 50m/s unless acted upon by an unbalanced force. Another aspect of the car that relates to Newton’s
