- Q3An elevator moves downward with a constant acceleration of 2 m/s² from rest. How far does it travel in 5 seconds?15 meters30 meters20 meters25 meters30s
- Q4An object moves in a straight line and covers a distance of 80 meters in 4 seconds. What is its average speed?30 m/s15 m/s20 m/s25 m/s30s
- Q5A ball is thrown horizontally from the top of a cliff with a speed of 20 m/s. If the cliff is 45 meters high, how long will it take for the ball to hit the ground?2 seconds5 seconds3 seconds4 seconds30s
- Q6What does a horizontal line on a distance-time graph represent?The object is moving at a constant speed.The object is accelerating.The object is moving backwards.The object is at rest.30s
- Q7On a distance-time graph, what does a steeper slope indicate compared to a gentler slope?A higher speed.The object is stationary.Constant acceleration.A lower speed.30s
- Q8What does the slope of a velocity-time graph represent?DisplacementSpeedDistanceAcceleration30s
- Q9Which of the following statements about free fall is true?All objects in free fall accelerate at the same rate regardless of their mass.Heavier objects fall faster than lighter objects.Objects in free fall come to rest after a few seconds.Air resistance affects all objects equally in free fall.30s
- Q10What is the formula for gravitational force according to Newton's law of universal gravitation?
F = G x d2 / (m1 x m2)
F = (G x m1 x m2) / d
F = m1 x m2 /d
F = (G x m1 x m2) / d2
30s - Q11Which of the following statements best describes Newton's law of universal gravitation?Gravitational force is only significant between large celestial bodies.Gravitational force is constant for all objects regardless of mass or distance.Gravitational force depends only on the mass of one object.Every particle in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.30s
- Q12What happens to the gravitational force between two objects if the distance between them is doubled?The gravitational force is quadrupled.The gravitational force is doubled.The gravitational force remains the same.The gravitational force is reduced to one quarter of its original value.30s
- Q13How does the gravitational force between two objects change if the mass of both objects is doubled while maintaining the same distance?The gravitational force increases by a factor of four.The gravitational force is halved.The gravitational force doubles.The gravitational force remains the same.30s
- Q14Which of the following best describes the nature of the gravitational force according to Newton's law?It only acts between objects on Earth and the Moon.It is an attractive force that acts between any two masses.It only acts at very short distances.It is a repulsive force that acts between any two masses.30s
- Q15According to Newton's first law of motion, what will happen to an object at rest if no external forces act on it?It will eventually come to a stop.It will start moving spontaneously.It will remain at rest.It will move in a circular path.30s
