Science Series 2026 - 05 (Physics) Motion Time Left: 10:00 Question 1: A curved line on a Distance-Time graph indicates: Uniform speed Non-uniform speed Object at rest Linear motion Submit Question 2: According to Newton?s Third Law, Action and Reaction forces: Act on the same body Act on different bodies Are in the same direction Cancel each other out Submit Question 3: The "inertia" of an object is directly dependent on its: Velocity Momentum Mass Surface area Submit Question 4: If no external force acts on a system of bodies, the total momentum remains: Zero Constant Variable Infinite Submit Question 5: A passenger in a moving train tosses a coin which falls behind him. This means the motion of the train is: Accelerated Uniform Retarded Circular Submit Question 6: The speed-time graph for a particle is a straight line not passing through the origin. This means: u = 0 s = 0 a = 0 u?0 Submit Question 7: Which of the following is responsible for keeping a body in a circular path? Centrifugal force Friction Inertia Centripetal force Submit Question 8: When a bullet is fired from a gun, the gun recoils. This is explained by: Newton`s 1st Law Newton`s 2nd Law Newton`s 3rd Law Law of Gravitation Submit Question 9: A body is said to be in "Retardation" when: Velocity is increasing Velocity is constant Velocity is decreasing Body is at rest Submit Question 10: The motion of a pendulum is an example of: Linear motion Periodic motion Uniform motion Circular motion Submit Question 11: A goalkeeper pulls his hands backwards while catching a fast-moving cricket ball. This is to: Reduce the force Increase the force Reduce the time Increase the momentum Submit Question 12: The "Law of Inertia" was first proposed by: Newton Galileo Einstein Kepler Submit Question 13: When a stationary bus starts suddenly, passengers tend to fall backwards. This is due to: Inertia of motion Inertia of direction Inertia of rest Gravitation Submit Question 14: If the mass of a body is doubled while the force remains constant, the acceleration will be: Doubled Halved Quadrupled Unchanged Submit Question 15: The momentum of an object at rest is: Infinite Negative Zero Constant but not zero Submit Question 16: A fielder catching a ball is an application of which law? Newton`s 1st Law Newton`s 2nd Law Newton`s 3rd Law Law of Gravitation Submit Question 17: Balanced forces acting on a body can change its: Speed Direction Shape Velocity Submit Question 18: Rocket propulsion works on the principle of conservation of: Mass Energy Linear Momentum Force Submit Question 19: If a force acts on a body, it must change its: Mass State of motion Color Temperature Submit Question 20: An unbalanced force acting on an object always produces: Constant speed Rest Acceleration Friction Submit Previous Next
