What affects the vertical component of a projectile's velocity?
Wiki User
∙ 11y ago
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

∙ 15y agomany forces act on an object in projectile motion
the air molecules exert a force on it
gravity exerts a force on it
the force that caused the projectile motion is involved in the objects path
so theres no single force that causes the path of an object in projectile motion, are you thinking of gravity?
Wiki User
∙ 14y agowell...projectile motion is made of two different motions, or movements- horizontal movement and vertical movement so... i guess that it
Wiki User
∙ 13y agoIn projectile motion, the force of gravity has no influence
on the horizontal component of velocity.
Wiki User
∙ 13y agoIgnoring air resistance, gravity has no effect at all on horizontal motion, but imparts
a downward acceleration of 9.8 meters (32.2 feet) per second2 on the vertical motion.
Wiki User
∙ 13y agoGravitational force only.
2. Air resistance has effect also.
Wiki User
∙ 11y agoGravity, initial velocity, the sine of the angle of launch, and air resistance all play a role in the vertical component of a projectile's velocity.
Wiki User
∙ 13y agoThe vertical component of projectile motion is influenced by the force of gravity,
regardless of the horizontal component.
Wiki User
∙ 11y agoIn ideal projectile motion, the only force present is the gravitational one.

How are gravity and velocity related?
gravity affects the momentum and velocity of an object. momentum=mass x velocity
Does friction affects velocity ratio?
No. The velocity ratio remains constant but the friction absorbs power.
Does friction affect speed or velocity?
Speed is a scalar (non-directional) representation of velocity. Friction affects the magnitude of both and the direction of velocity.
A bullet fired horizontally over level ground hits the ground in 0.5 seconds If it had been fired with twice the speed in the same direction it would have hit the ground when?
Assuming no affects from air and a smooth geography, both bullets would fall at the same rate of 9.81 m/s^2 toward earth, and hit the ground simultaneously. You have to look at the bullet's velocity as having a horizontal and vertical velocity vectors. The vertical velocity vector is independent from that of the horizontal. The horizontal vector would be the speed at which the bullet is fired, and the vertical vector is the speed at which the bullet falls due to gravity.
What affects an objects inertia?
The mass of the object and the velocity of the object.
How are gravity and velocity related?

A projectile fired from the ground follows a parabolic path The speed of the projectile is minimum at the top of its path?
Yep that is correct. To understand this it may help you to draw a parabola. If you draw a line from the top of the parabola back to the ground you'd notice either side of this line is symmetrical. This isn't quite what happens to a projectile (following a parabolic path), but because of the nature of the question, effects such as air resistance can be ignored. As the projectile approaches the top of its path, the vertical component of its velocity approaches zero. As the projectile begins to fall the magnitude of the vertical component of the projectile begins to increase. The only force that acts on the projectile during flight is gravity which pulls it towards the earth. Since this force and the horizontal component of the projectiles velocity are at right angles to each other, the horizontal component of the velocity is unaffected during flight . This explains the symmetry of the parabola and also means the time to reach the top of path equals the time from the top of path back to the ground. The projectile will hit the ground with the same speed as it left the ground. If you draw a horizontal line through the parabola, at the two points where the line and the parabola cross, the speed of the projectile will be the same. The only change to the balls speed during the flight comes as the vertical component of its velocity tends to zero as it reaches the top of the curve and then falling back down due to gravity. I'm unsure of your physics knowledge but hopefully this doesn't confuse you. If you have learned about vectors, then this can be simply understood/explained.

No. The velocity ratio remains constant but the friction absorbs power.
What affects inertia?
Gravity affects inertia. The lower the gravity, the more inertia.

The medium through which sound waves travel affects the?
Velocity.
What affects an objects inertia?
The mass of the object and the velocity of the object.
What affects frequency?
Velocity (relative and absolute), medium of transmission, ...
What would happen to an object in free fall?
The velocity in the x direction would be constant because gravity only affects the vertical components of objects. The velocity in the y direction would increase due to the constant acceleration due to gravity. The acceleration due to gravity on Earth is always -9.81 m/s^2.
What affects bed load?
The velocity and discharge volume of the stream or river.
How Does Vertical air affects pressure at the surface?
Yes the surface pressure is caused by the weight of the vertical column of air above a surface.
