has the greater acceleration: the bat or the ball? Two identical small cars (car A & car B) have a head-on collision. Which scenario is true? Car A exerts a greater force on car B than car B exerts on car A. Car B exerts a greater force on car A than car A exerts on car B. The force that car A exerts on car B and the force that car B exerts on car A are the same magnitude. Consider question 3. Which has the greater acceleration: car A or car B? They have the same acceleration. A large truck

another object. Whenever there is an interaction between two objects‚ there is a force upon each of the objects. When the interaction ceases‚ the two objects no longer experience the force. Forces onlyexist as a result of an interaction. Velocity‚ Acceleration‚ Momentum‚ and Impulse Velocity‚ in physics‚ is a vector quantity (it has both magnitude and direction)‚ and is the time rate of change of position (of an object). However‚ quite often when you read ‘velocity’‚ what is meant is speed‚ the magnitude

hip joint is a ball and socket joint‚ which means it can move in all directions. The knee joint is a compound condylar synovial joint and allows for flexion and extension of the leg. In this experiment the angle‚ angular velocity‚ and the angular acceleration of the knee and hip were analyzed in oscillatory motion. In the first set of experiments‚ the independent oscillation of the hip and knee were isolated and observed. Then the oscillation of these joints was viewed in conjunction while a subject

truth to space -- that spatial differences are not dependent upon the matter contained within space. In his Principia‚ he states that the difference of relational and absolute space becomes manifest in the consideration of place‚ velocity‚ and acceleration. These considerations serve to metaphysically establish absolute space in themselves. However‚ Newton attempts to support the existence experimentally in his famous ’bucket experiment’. Through an explication of his reasoning and an analysis

The car that weighs the most will go farther because it has a higher speed and momentum. Gravity has a huge effect on the way a toy car rolls downhill or down a slope. The cars mass‚ velocity‚ acceleration have an effect to. Acceleration is the rate at which an object speeds up. The car’s acceleration point is during the middle of the slope. Momentum ‚which is how strong a moving thing is‚ happens also in the middle of the slope or hill. As the toy car falls it accelerates and picks up momentum

predict the landing point when the projectile is fired at a nonzero angle of elevation. EQUIPMENT Spring gun Metal ball Protractor Meter stick Ruler Whiteboard markers THEORY Projectile motion is an example of motion with a constant acceleration. In this experiment‚ a projectile will be fired from some height above the floor and the position where it lands will be predicted. To make this prediction‚ one needs to know how to describe the motion of projectile using the laws of physics. The

Time Uncertainty The uncertainty in time remains the same for part 2. Gravity can be determined by comparing acceleration and mass ratio. Theoretically‚ this number should not be significantly different than the local gravity calculated in lab 1. Gravity was determined in lab 1. “Free Fall”‚ using Google earth‚ and is shown below.

distance‚ time‚ and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed‚ distance‚ time‚ and acceleration. Distance and time are two formulas that are used to determine speed and time. For example‚ distance equals speed multiplied with time given‚ time equals distance divided by speed‚ and speed is equals distance divided time. Speed and time are required to determine acceleration.

little wide and lose‚ and the flaps were not arrow dynamic what so ever. To improve the flight I could have made my rocket shorter and thinner because the smaller the mass the greater acceleration. Doing this would improve the acceleration of the projectile in this case the rocket. Also to improve the acceleration I could add more alka-seltzer to the film case. Doing this would add a greater force to push off of which would make the rocket go higher and faster. Lastly I could have made the structure
