Which of the following describe a projectile motion?
A motion in a straight line.
A motion that follows a circular path.
A motion that is not influenced by gravity.
A motion that is influenced by gravity and horizontal velocity.
What are the two components of the projectile motion?
Backward and Forward
Downward and upward
Horizontal and Vertical
Inner and outward
Which of the following causes the object in a projectile motion to move downward?
Acceleration
Gravity
Momentum
Speed
Which of the following refers to the horizontal distance travelled by an object in a projectile motion?
Gravity
Height
Parabola
Range
Why does the horizontal component of a
projectile’s motion remain constant?
Because no force acts on it vertically.
Because no force acts on it horizontally.
Because force acts on it horizontally.
Because force acts on it vertically.
Why does the vertical component of a projectile’s motion undergo change?
Because velocity is pulling it downward
Because gravity is pulling it downward.
Because gravity is pushing it upward
Because gravity is pulling it horizontally.
A projectile is launched vertically at 100 m/s. If air resistance can be neglected, at what speed does it return to its initial level?
1 m/s
10 m/s
100 m/s
1000 m/s
The path of a projectile is called ____________.
Parabola
Height
Range
Trajectory

9.8 m/s2
98.0 m/s2
198.0 m/s2
980 m/s2
The horizontal and vertical components of the initial velocity of a football are 16 m/s and 20 m/s
respectively. How long does it take for the football to rise to the highest point of its trajectory?
2.0 s
1.0 s
3.0 s
4.0 s
A ball rolls off the edge of a table. The horizontal component of the ball's velocity remains constant
during its entire trajectory because
the ball is not acted upon by any force.
the net force acting on the ball is zero.
the ball is not acted upon by a force in the horizontal direction.
None of the other choices is correct.
An athlete throws a ball with a velocity of 40 m/s at an angle of 20e above the horizontal. Which of the following statements is true in this case?
The vertical component of the velocity remains constant.
The horizontal component of the velocity changes.
The vertical component of the velocity changes sign after the ball attains its maximum height.
The horizontal component of the velocity changes sign after the ball attains its maximum height.
How does the video clip justify that horizontal motion of a projectile is independent of its vertical motion?
The horizontal velocity of a projectile dropped from a moving object is the (a) as the velocity of the
moving object.
The vertical component of a projectile’s motion is (a) to the horizontal component of its
motion.
