1. GENERAL PHYSICS QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
Speed= - ANSWER distance÷time



What is the shape of a distance-time graph when the object is at rest? - ANSWER a horizontal line



What is the shape of a distance-time graph when the object is moving with constant speed? - ANSWER a
slanted line



What is the shape of a distance-time graph when the object is moving with changing speed? - ANSWER a
curved line



What is the distance traveled for motion with constant acceleration in a speed-time graph? - ANSWER
the area under the graph



If a body accelerates its speed-time graph will have a... - ANSWER positive gradient



If a body decelerates its speed-time graph will have a... - ANSWER negative gradient



What is the difference between speed and velocity? - ANSWER Velocity is a vector while speed is scalar.
Velocity has a direction.



a = - ANSWER ∆v÷t



Speed (on a distance-time graph) = - ANSWER the gradient



Acceleration (on a speed-time graph) = - ANSWER the gradient



On a speed-time graph, a straight line with a positive gradient means... - ANSWER constant acceleration

, On a speed-time graph, a curved line with a positive gradient means... - ANSWER changing acceleration



Deceleration= - ANSWER negative acceleration



The mass of a body = - ANSWER the number of particles it has



Weight is a _____________ force - ANSWER gravitational



What is the difference between mass and weight? - ANSWER Weight is affected by gravitational field
strength



W(Weight) = - ANSWER m×g



How do you compare weights using balance? - ANSWER You put a weight on each side of the balance
then whichever way the balance leans is the heaviest.



What is 'inertia'? - ANSWER It is the idea that if a force is applied to an object, it will not immediately
reach a high speed because it requires time to accelerate, as shown by the formula F=ma.



Weight (definition) = - ANSWER A body's mass multiplied by the strength of the gravitational field around
it.



ρ = - ANSWER m×V



Describe an experiment to determine the density of a liquid and of a regularly shaped solid. - ANSWER
Find the mass by weighing the object on a scale and then use a measuring cylinder to find the volume.
Then divide the mass by the volume to get the density in (g/cm³)



Describe the determination of the density of an irregularly shaped solid by the method of displacement.
- ANSWER First, fill a Eureka can to the level of the spout, then lower the solid into the water. Pour the
water collected out of the spout into a measuring cylinder. That is the volume of the solid. Then, weigh
the mass and apply the density formula (ρ = m×V) to calculate the density.
