Motion and Time multiple choice questions and answers on motion and time MCQ questions quiz on motion and time objectives questions.

1. A ball is thrown with a velocity of 20 m/s at an angle of 60^{o} above the horizontal. What is the horizontal component of its instantaneous velocity at the exact top of its trajectory?

- 17 m/s
- 10 m/s
- zero
- 20 m/s

2. A bullet is fired horizontally, and at the same instant a second bullet is dropped from the same height. Ignore air resistance. Compare the times of fall of the two bullets.

- The fired bullet hits first.
- They hit at the same time.
- The dropped bullet hits first.
- cannot tell without knowing the masses

3. A package of supplies is dropped from a plane, and one second later a second package is dropped. Neglecting air resistance, the distance between the falling packages will

- depend on their weight.
- increase.
- be constant.
- decrease.

4. A pilot drops a bomb from a plane flying horizontally at a constant speed. Neglecting air resistance, when the bomb hits the ground the horizontal location of the plane will

- be over the bomb.
- be behind the bomb.
- depend on the speed of the plane when the bomb was released.
- be in front of the bomb.

5. At what angle should a water-gun be aimed in order for the water to land with the greatest horizontal range?

- 30
^{o} - 60
^{o} - 45
^{o} - 0
^{o}

6. If the acceleration of an object is always directed perpendicular to its velocity

- this situation would not be physically possible.
- the object is slowing down.
- the object is speeding up.
- the object is turning.

7. If the acceleration vector of an object is directed anti-parallel to the velocity vector

- the object is turning.
- the object is slowing down.
- the object is speeding up.
- the object is moving in the negative x-direction.

8. Ignoring air resistance, the horizontal component of a projectiles acceleration

- continuously decreases.
- continuously increases.
- is zero.
- remains a non-zero constant.

9. Ignoring air resistance, the horizontal component of a projectiles velocity

- remains constant.
- is zero.
- continuously increases.
- continuously decreases.

10. The acceleration of gravity on the Moon is only one-sixth of that on Earth. If you hit a baseball on the Moon with the same effort (and at the speed and angle) that you would on Earth, the ball would land

- one-sixth as far.
- the same distance away.
- 6 times as far.
- 36 times as far.
