- Q1According to Newton's second law of motion, what happens to the acceleration of an object when the net force acting on it increases?It remains constantIt increasesIt decreasesIt becomes zero30s
- Q2Which of the following best describes Newton's first law of motion?An object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by an external forceAn object's velocity increases as the net force acting on it increasesThe acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its massFor every action, there is an equal and opposite reaction30s
- Q3According to Newton's third law of motion, what happens when a force is applied to an object?The object remains at restThe object accelerates in the direction of the applied forceThe force is increasedAn equal and opposite force is applied back to the object30s
- Q4What is inertia?The force required to stop an objectThe tendency of an object to resist changes in its motionThe force exerted on an objectThe rate at which an object changes its velocity30s
- Q5What is the relationship between mass and inertia?Mass determines an object's accelerationMass is the speed of an objectMass is a measure of inertiaMass is the force experienced by an object30s
- Q6What is the relationship between speed and distance?Speed is the time taken to travel a given distanceSpeed is the distance traveled per unit of timeSpeed is the force applied to an objectSpeed is the resistance to motion30s
- Q7What is the measure of how quickly an object changes its velocity?SpeedAccelerationVelocityInertia30s
- Q8Which term describes the resistance of an object to changes in its motion?AccelerationVelocityInertiaSpeed30s
- Q9Which term represents the amount of distance an object travels in a given time?AccelerationVelocitySpeedInertia30s
- Q10Which of the following is an example of inertia?A rocket launching into spaceA skateboarder performing tricks on a halfpipeA soccer ball rolling on a flat field and eventually coming to a stopA car accelerating from rest to a high speed30s
- Q11Which of the following is an example of an application of Newton's first law of motion?A car stopping suddenly and the passengers lurching forwardA hockey puck sliding on ice with minimal resistanceA rocket launching into spaceA basketball bouncing off the ground after being dropped30s
- Q12A car travels a distance of 100 kilometers in 2 hours. What is its average speed?50 kilometers per hour100 kilometers per hour75 kilometers per hour25 kilometers per hour30s
- Q13A boat travels a distance of 40 kilometers in 2.5 hours. What is its average speed?16 kilometers per hour20 kilometers per hour30 kilometers per hour10 kilometers per hour30s
- Q14A train travels a distance of 300 kilometers in 4 hours. What is its average speed?75 kilometers per hour100 kilometers per hour50 kilometers per hour200 kilometers per hour30s
- Q15What happens to the force of gravity between two objects when the distance between them increases?It increasesIt decreasesIt becomes zeroIt stays the same30s
