Multiple Choice Question 6.31 A 1000-kg car moving at 10 m/s brakes to a stop in 5 s. The average braking force is 3000 N 5000 N 2000 N ***(answer) 1000 N 4000 N Force = mass x acceleration. Acceleration = velocity/time = -10/5 = -2 m/s/s. (- sign means a deceleration from velocity of 10 to 0) Force = 1000 x -2 = -2000 Newtons (i.e. 2000N in opposite direction to motion) Multiple Choice Question 6.11 When you jump from an elevated position you usually bend your knees upon reaching

adrenaline junkies and thrill seekers. The sport involves jumping from a tall structure‚ being a building‚ bridge or crane‚ while secured to a nylon-cased rubber band8. While the sport is enthralling‚ it is extremely dangerous and requires knowledge of physics and physical phenomena. Knowledge of the energy transformations involved in bungee jumping are required to complete calculations‚ which determine safe jumping conditions. This proposal will explore the parameters and ideas of possibly operating a

Sunlight and Concave Mirror for Cooking Researchers: Pamatmat‚ Mikaela Franchesca Siacon‚ Maria Sherlene Dianne Cruz‚ Jeremy Anne Lardizabal‚ Zaree Dominique Macagba‚ Danielle Martinez‚ Kyrene Teacher: Sir Vincent Sabong Abstract The researchers thought of trying to come up with a makeshift solar cooker in order to test if this way of cooking may be effective and useful in substituting for a frying pan and a stove. The solar cooker may be a possible alternative when cooking outdoors under

HSC Physics Space 1. The Earth has a gravitational field that exerts a force on objects both on it and around it Define weight as the force on an object due to a gravitational field Mass is a measure of the amount of matter in an object‚ it is measured in kilograms (kg). The weight of an object is a measure of the force with which it is attracted by a gravitational force‚ it is measured in Newtons (N). It is directly related to the strength of the gravitational field at a point where the object

RESEARCH PAPER IN PHYSICS By: Sharmaine Joyce T. Sebastian B.S PT 2A2-1 College of Physical Therapy Sebastian‚ Sharmaine Joyce T. December 2‚ 2013 1. Why an ice cube at 0°C is more effective in cooling soft drink than the same mass of water at 0 °C? Enthalpy of fusion is the change in enthalpy resulting from heating a given quantity of a substance to change its state from a solid to a liquid. The temperature at which this occurs is the melting point would

The Physics of Field Goal Kicking Physics is involved in all of our daily activities. Most of the time‚ however‚ physics is overlooked and never acknowledged. It is important to understand different aspects of physics because physics tells us how and why certain events occur. By definition‚ physics is the search for laws that describe the most fundamental aspects of nature: matter‚ energy‚ force‚ motion‚ heat‚ light‚ and other phenomena. There are many different sectors of physics‚ but we will
