The percentage error between the theoretical value of initial velocity measured with photo gate and lab quest and the experimental value calculated with kinematics is 0.02473%.

a consistent velocity unless acted upon by a net force. A real world example of this would be playing golf. The golf ball sits on the tee with no momentum‚ nor force acting upon it (excluding the force of gravity). And when the club comes through to hit it‚ it generates a greater net force and moves through the ball with a certain velocity. The momentum from the club is then transferred from the club‚ to the ball. When the ball is in the air‚ it is moving at a constant velocity but is being acted

This is due to the shape of the blade on the skates. Angular momentum applies to a body rotation around a fixed object. The amount of

Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

conservation of momentum can be a huge effect on the cars‚ so the conservation of momentum states that when there are no other outside forces like friction the total momentum of the objects interaction does not change. The amount of momentum before and after the collision will be the same. If this is the case then the momentum of the first car‚ mass times velocity‚ does not change the momentum of the second car if the second car is at rest so the second car would have the same momentum as the first

presents a better chance of stopping the momentum of the offensive player altogether. According to Timothy Gay‚ physics professor at the University of Nebraska‚ when a defensive player tackles low‚ there is a chance that the offensive player will spin out of the tackle because the center of mass of the player remains in forward motion. When a defensive player instead applies his momentum to or just below the center of mass of the offensive player‚ the momentum of the offensive player is stopped and

Libet wanted subjects to feel like they were in control and therefore did not attempt to force an action to occur. Brain impulses‚ initiated unconsciously‚ were recorded before the subject was initially aware of any intention to act. Libet called the measure of these brain impulses readiness potentials. He

Purpose: This paper is to identify and explain the in-store shopping environment effects that drive consumers’ impulse buying decisions. Methodology: Primary data is collected from 100 randomly selected shoppers in Abbottabad and Islamabad. Descriptive data analysis along with test of significance was applied to analyze data. Findings: Results indicate that presence of an enjoyable‚ pleasant and attractive in-store shopping environment increases the chances of impulsive buying among consumers
