- Q1What is momentum?The force acting on an object.The product of an object's mass and velocity.The energy stored in an object.The distance traveled by an object.The time it takes for an object to change its velocity.30s
- Q2Which of the following has the greatest momentum?A bicycle moving at 10 miles per hour.A car moving at 50 miles per hour.A person walking at 2 miles per hour.A scooter moving at 5 miles per hour.A train moving at 30 miles per hour.30s
- Q3Which of the following statements about momentum is true?Momentum is always equal to the velocity of an object.Momentum depends only on the mass of an object.Momentum can be negative but never positive.Momentum is conserved in a closed system.Momentum increases with decreasing velocity.30s
- Q4A ball with a mass of 0.5 kg is moving with a velocity of 10 m/s. What is its momentum?5 kg*m/s10 kg*m/s20 kg*m/s15 kg*m/s7 kg*m/s30s
- Q5Two objects with different masses are moving with the same velocity. Which object has more momentum?The object with greater mass.None of the above.The object with smaller mass.Both objects have the same momentum.Momentum depends on velocity, not mass.30s
- Q6Which of the following options correctly describes the law of conservation of momentum?Momentum is directly proportional to mass.The momentum of an object can never change.Momentum is only conserved in isolated systems.The total momentum of a closed system remains constant unless acted upon by an external force.Momentum increases as velocity increases.30s
- Q7A body with a mass of 2 kg is moving with a velocity of 4 m/s. What is its momentum?2 kg*m/s8 kg*m/s16 kg*m/s32 kg*m/s4 kg*m/s30s
- Q8What is the acceleration of an object in freefall?0 m/s²5 m/s²20 m/s²9.8 m/s²30s
- Q9What is freefall?The motion of an object falling under the influence of gravity.The motion of an object propelled upwards.The motion of an object on a flat surface.The motion of an object in zero gravity.30s
- Q10What is the height of an object dropped from a tower, after 3 seconds of freefall?9.8 meters44.1 meters19.6 meters29.4 meters30s
- Q11Which unit is commonly used to measure time?MeterCelsiusKilogramSecond30s
- Q12What is the equivalent of 50 degrees Celsius in Fahrenheit?122212683230s
- Q13What is 4000 meters in kilometers?40.40.044030s
- Q14What is the equivalent of 5.6 kilometers in meters?5656056000560030s
- Q15What is the difference between accuracy and precision?Accuracy refers to the consistency of a measured value, while precision refers to the closeness of a measured value to a true or target value.Accuracy refers to the highest possible value that can be reached, while precision refers to the lowest possible value that can be reached.Accuracy refers to the ability to measure small values, while precision refers to the ability to measure large values.Accuracy refers to the closeness of a measured value to a true or target value, while precision refers to the consistency or reproducibility of a measured value.30s
