1
What is displacement? A.Term correct B.Units Correct C.Quantity type correct. D.None correct Displacement of an object is a vector quantity representing a change in its position. Basic MKS or SI unit is meters=m (other units are km,miles,feet, furlong,…)

2
What is velocity? A.Term correct B.Units Correct C.Quantity type correct. D.None correct The velocity of an object is a vector quantity representing the rate of change of its position accounting for direction. Basic MKS or SI unit is meters/second=m/s (other units are km/hour,miles/hour, furlong/fortnight,…) The speed of an object is a scalar quantity representing the magnitude of the rate of change of position not accounting for direction. Basic MKS or SI unit is meters/second (other units are km/hour,miles/hour, furlong/fortnight,…)

3
What is acceleration? A.Term correct B.Units Correct C.Quantity type correct. D.None correct The acceleration of an object is a vector quantity representing the rate of change in its velocity. Basic MKS or SI unit is m/s/s=m/s 2.

4
What is mass? A.Term correct B.Units Correct C.Quantity type correct. D.None correct In kinematics, the mass of an object is a scalar quantity representing the resistance of a body to being accelerated by a force. Basic MKS or SI unit is kilogram =kg (other units are pounds, ounces, stone,…)

5
What is momentum? A.Term correct B.Units Correct C.Quantity type correct. D.None correct The momentum of an object is a vector quantity derived from the product of its mass with its velocity. Basic MKS or SI unit is kg-m/s.

6
What is Force? A.Term correct B.Units Correct C.Quantity type correct. D.None correct The force acting on an object is a vector quantity derived from the product of mass with acceleration. Basic MKS or SI unit is kg-m/s 2 =N (Newton).

7
What is kinetic energy? A.Term correct B.Units Correct C.Quantity type correct. D.None correct The kinetic energy of an object is a scalar quantity representing the energy of an object due to its motion. Basic MKS or SI unit is kg-m 2 /s 2 = Joule.

8
What is potential energy? A.Term correct B.Units Correct C.Quantity type correct. D.None correct The kinetic energy of an object is a scalar quantity representing the energy of an object due to its position. Basic MKS or SI unit is kg-m 2 /s 2 = Joule.

9
What is Power? A.Term correct B.Units Correct C.Quantity type correct. D.None correct In mechanical systems, power is a scalar quantity equal to the scalar product of Force and velocity of an object. Basic MKS or SI unit is kg-m 2 /s 3 = Joule/s=Watt.

10
Quadratic Equation A.Simplified expression correctly B.Term correct C.Solutions correct D.Name of equation correct E.None correct x 2 +2hx+h 2 =(x+h) 2 Procedure is known as Completing the Square Solutions to ax 2 +bx+c=0 Name is Quadratic Equation
