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
many 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?
well...projectile motion is made of two different motions, or movements- horizontal movement and vertical movement so... i guess that it
In projectile motion, the force of gravity has no influence
on the horizontal component of velocity.
Ignoring 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.
Gravitational force only.
2. Air resistance has effect also.
Gravity, 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.
The vertical component of projectile motion is influenced by the force of gravity,
regardless of the horizontal component.
In ideal projectile motion, the only force present is the gravitational one.
gravity
gravity affects the momentum and velocity of an object. momentum=mass x velocity
No. The velocity ratio remains constant but the friction absorbs power.
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.
Speed is a scalar (non-directional) representation of velocity. Friction affects the magnitude of both and the direction of velocity.
The mass of the object and the velocity of the object.

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.
Gravity affects inertia. The lower the gravity, the more inertia.

Velocity.
The mass of the object and the velocity of the object.
Velocity (relative and absolute), medium of transmission, ...
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.
The velocity and discharge volume of the stream or river.
Yes the surface pressure is caused by the weight of the vertical column of air above a surface.
