THEORY
Instruction: Answer three questions only
Write three examples each of fundamental and derived quantities
Write the dimensions and units of the quantities listed above
Draw a velocity time graph showing when a vehicle is:
At rest
Moving in constant speed
Constant acceleration
Constant deceleration
A motor car accelerates for 10 seconds to attain a velocity of 20m/s. it continues with uniform velocity for a further 20 seconds and then decelerates so that it stops in 20 seconds. Draw the velocity time graph representation and calculate:
(i). Acceleration
(ii). Deceleration
(a). Define motion and friction(b). List the two types of force and explain one
(c). List four types of motion and explain
Define the following:
(a). Speed
(b). Velocity
(c). Position
(d). Displacement
(e). Distance
(f). Scalar quantity
(g). Vector quantity
1. Speed is defined as the rate of change of position of an object with respect to time. It is a scalar quantity and is represented by the formula: speed = distance/time.
2. Velocity is defined as the rate of change of displacement of an object with respect to time. It is a vector quantity and is represented by the formula: velocity = displacement/time.
3. Position is defined as the location of an object with respect to a reference point.
4. Displacement is defined as the change in position of an object with respect to a reference point. It is a vector quantity and is represented by the formula: displacement = final position – initial position.
5. Distance is defined as the length of the path travelled by an object. It is a scalar quantity and is represented by the formula: distance = velocity × time.
6. Scalar quantity is a quantity that has magnitude only and no direction.
7. Vector quantity is a quantity that has both magnitude and direction.
