Projectile motion always involves downward movement?
This is not true. Projectile motion consists of an object moving in a two-dimensional plane under the influence of gravity. While the vertical component of the motion may involve a downward movement, the horizontal component can be in any direction.
What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
Why gravitationalforce is taken negative in projectile motion?
Gravitational force pulls downward. If you take the upward direction as positive, then any force that pulls downward will be negative. It is a matter of definitions; you can just as well define up as negative, and down as positive. It doesn't really matter much, one way or the other.
What is the only force acting upon a projectile?
The only force acting on a projectile is gravity. It causes the projectile to accelerate downward and follow a curved path. The horizontal motion of the projectile is not affected by any other forces.
How does the downward component of the motion of a projectile compare to the motion of vertical free fall?
The downward component of the motion of a projectile is the same as vertical free fall. Both are affected by gravity pulling the object downward at a constant rate of 9.8 m/s^2 on Earth. The only difference is that a projectile also has a horizontal component of motion due to an initial velocity.

Which is the only active force a projectile is any moving object upon?
The only active force acting on a projectile is gravity. Once the object is released, the only force affecting its motion is the force of gravity pulling it downward.

What two forces acting on a projectile?
The two main forces acting on a projectile are gravity, which pulls the projectile downward, and air resistance, which acts in the opposite direction to slow down the projectile's motion. Other forces, such as propulsion or wind, can also affect the motion of a projectile.
Does the force act on a projectile?
Yes, a force such as gravity acts on a projectile, influencing its trajectory and motion. The force of gravity accelerates the projectile downward, affecting its path and causing it to follow a curved trajectory.
Which of thesse is true of a person walking up the steps of a downward moving escalater at a constant speed?
The person is walking faster than the escalator is moving downward in order to reach constant speed.
The moving ball in this illustration can be called a?
Projectile on A+
What can the moving ball in this illustration be called?
projectile
What is the vertical velocity of a projectile at the highest point in its trajectory?
At the highest point in its trajectory, the vertical velocity of a projectile is zero. This is because the projectile has reached its peak height and is momentarily at rest before starting to descend.
