- Q1What is the vertical component of velocity at the highest point of projectile motion?It is zeroIt is constantIt is positiveIt is negative30s
- Q2How does the angle of projection affect the range of a projectile?The range is maximum when the angle of projection is 0 degreeThe range is maximum when the angle of projection is 90 degreesThe range is maximum when the angle of projection is 45 degreesThe angle of projection does not affect the range30s
- Q3What happens to the time of flight of a projectile when the initial velocity is doubled?It remains the sameIt is doubledIt is quadrupledIt is halved30s
- Q4What is the maximum height reached by a projectile?It is always equal to the range of the projectileIt is always the same regardless of initial conditionsIt depends on the initial velocity and the angle of projectionIt is directly proportional to the mass of the projectile30s
- Q5When a projectile is launched at an angle of 90 degrees (straight upward), what is the direction of its initial velocity?Vertical downwardHorizontalNo initial velocityVertical upward30s
