 Side A Side B 1 1. Distinguish between distance and displacement. Distance is a scalar measure of the interval between two... 2 2. Distinguish between speed and velocity. Speed is the rate of change of distance with time.   Velocity... 3 3. Define and classify vector and scalar quantities. Vectors-  weight, acceleration, force, momentum, displacement. Scalars-... 4 4. State what is meant by the resultant of a number of forces. The resultant vector is a single vector which represents the combined effect of a numberof... 5 5. State that acceleration is the change in velocity per unit time. - 6 6.Describe the principles of a method of measuring acceleration. Measurement of acceleration :To measure the acceleration of an object we require to measure... 7 7.Define the Newton. unit of force equal to the force that imparts an acceleration of 1 m/sec/sec to a mass... 8 8. State that momentum is a product of mass and velocity. - 9 9.State that the law of conservation of momentum can be applied to the interaction of two objects... - 10 10.State that an elastic collision is one in which momentum and kinetic energy are conserved. - 11 11.State that an inelastic collision is one in which only momentum is conserved. - 12 12. State that impulse = force x time. - 13 13. State that impulse = change in momentum. - 14 14.State that density is mass per unit volume. - 15 15. Describe the principles of a method of measuring the density of air. 1. Air is pumped into a RIGID container then valve is closed. 2. Container is... 16 16. State and explain the relative magnitudes of the densities of solids, liquids and gases. Solid/Liquid = 1x1x1. Gas= 10x10x10. 17 17. State that pressure is force per unit area. - 18 18.State that one pascal is one newton per square metre. - 19 19. State that the pressure in a fluid at rest varies directly with depth and density. - 20 20 .Explain buoyancy and flotation in terms of the forces acting on a body. Upthrust. An object, immersed in a liquid ora gas experiences a force whichacts vertically... 21 21. State that the pressure of a fixed mass of gas varies inversely as the volume provided... - 22 22. State that the pressure of a fixed mass of gas at constant volume varies directly as its... - 23 23. Explain what is meant by absolute zero of temperature. Absolute zero is the theoretical temperature at which entropy reaches its minimum value. 24 25.Describe how a kinetic model accounts for the pressure of a gas. Pressure-The pressure exerted by a gas on the sides of its container is caused by gas particles...
