What affects the vertical component of a projectile's velocity?
The effect that gravity has on the vertical component of the projectile is that as the projectile is going upward it is decreasing 10m/s ever second it is going upward until it reaches its peak. at its peak its vertical component is zero. Then as it is going back to earth it is increasing at 10 m/s every second that is it going downward. for example, a boy throws a ball at 20 m/s upward its velocity after 2 seconds will be zero due to the fact that gravity canceled out the force and then.. what is the velocity after 4 seconds? it is 20 m/s.. gravity added 10 m/s ever second that it was falling to the earth. hope this helps
What type of path does a projectile follow in the absence of air resistance?
Without air resistance, the path of a projectile over a small part of the Earth's surface, under the influence of gravity alone, is always a piece of a parabola ... as long as it's not launched straight up or straight down.
What is the result of thecombination of an object's forward inertia and the downward pull of gravity on the object?
The result of the gravitational force is that the object accelerates downward.When that's combined with its constant horizontal speed, the object follows apath that curves downward, and is actually a piece of a parabola.In general, the motion of objects with some horizontal speed under the influence ofgravity is called "projectile" motion, because when the effect of air resistance isignored, it describes the motion of things like javelins, cannonballs, and burned-outrockets. It's a favorite subject commonly found in elementary Algebra and Physics.
What is the curved path an object follows when thrown?
If there's no influence from air resistance, then the path of a "projectile" is a parabola. That's what you get when one component of velocity is constant and its other (orthogonal) component is accelerated.
How are the horizontal velocity and the vertical velocity of thrown objects related?
If you can ignore air resistance, they're not. Neither component has any influence on the other one unless the object is acting as an airfoil.
What is the trajectory of the projectile?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
What is the shape of a projectile trajectory?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
What is projectile velocity?
Velocity is the time rate of change of displacement of an object. Velocity is the distance travelled in unit time in a stated direction. It is a vector quantity since it gives us both magnitude and direction.
What would you call an object that moves through the air under the influence of gravity?
That would be a projectile.
What is the factor influence the distance and time in projectile motion?
projection speed projection angle projection height

At what part of the trajectory does a projectile have maximum speed?
The maximum speed of a fired projectile, unless fired downward in a vacuum, is the muzzle velocity - this is when the propulsive acceleration ceases. Ignoring air resistance, the projectile would maintain its horizontal velocity, while gravity would first reduce then restore the vertical component. Terminal velocity, the maximum possible atmospheric speed, is determined by mass, gravity, air density, and projectile shape, as gravitic acceleration is slowed by air resistance.
Is it correct to say big influence or large influence?
It is correct to say "big influence." "Large influence" is not commonly used in English to describe influence.

Does cultural dimensions influence cross national agreement?
Yes, cultural dimensions can influence cross-national agreement as different cultures may have varying values, norms, and communication styles that can impact how individuals from different countries understand and negotiate agreements. Understanding and respecting cultural differences is important in order to facilitate successful cross-national agreements.
