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

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

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
