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 two types of motion does projectile motion include?
projectile motion means means the motion of a particle under the effect of gravity after being given some initial velocity by an external force. its path called trajectory is parabolic. so it includes motion in both x and y axes. the difference being that in x axis it is uniform motion and in y axis it is accelerated motion
The path taken by a missile or projectile?
The path taken by a missile or projectile is determined by its initial velocity, angle of launch, and external forces like gravity and air resistance. This path is usually a parabolic curve known as a projectile trajectory. The trajectory can be calculated using physics equations such as the kinematic equations of motion.
How do you determine the initial velocity in projectile motion?
To determine the initial velocity in projectile motion, you can use the equation v (x y) / t, where v is the initial velocity, x is the horizontal distance traveled, y is the vertical distance traveled, and t is the time taken.
What are the factors influencing projectile motion?
The motion of a projectile can be completely described in terms of ...the direction in which it is launchedits speed at launchthe local acceleration of gravityplus, if air resistance is to be taken into account ...the projectile's size, shape, weight, mass distribution, composition, and surface texturethe temperature, pressure, humidity, wind speed, and turbulence parametersof the air it encounters at every point in its trajectory.That's why air resistance is always ignored for simple exercises in projectile motion.
How does ballistic refer to projectile motion?
The term ballistic refers to the trajectory or path taken by a projectile. Normally it refers to that part of a projectiles flight that is unpowered and unguided except by the forces of gravity and (if applicable) air resistance.
Are there projectiles among animals?
I think the question is about projectile motion, Yes the animals jumping is the best example of projectile motion, when they jump a parabolic curve is formed thus their jumping could be taken as an example of projectile motion.......
What type of motion do catapults create?
Projectile motion also known as trajectory this is one of the most famous examples of motion in two dimensions in other words a projectile experience motion in the horizontal and the vertical. the path taken by a projectile looks like a parabola (but it is not necessary for it to be a complete one ) there are some famous examples of trajectories like the motion set by a catapult or the motion set by a bullet.
Are centripetal acceleration and projectile motion the same thing?
Centripetal acceleration at a constant velocity and projectile motion are realistic comparisons, but only in this particular scenario. It should be noted that the vector quantity of both needs to be taken into consideration when answering this question. The vector component of centripetal acceleration moves inward, while outward for projectile motion. So, in essence, centripetal acceleration and projectile motion are not the same thing.

Why projectile angle increase when projectile range also increase?
Range of a projectileThe path of this projectile launched from a height y0 has a range d.In physics, a projectile launched with specific initial conditions in a uniform gravity field will have a predictable range. As in Trajectory of a projectile, we will use:g: the gravitational acceleration-usually taken to be 9.80 m/s2 (32 f/s2) near the Earth's surfaceθ: the angle at which the projectile is launchedv: the velocity at which the projectile is launchedy0: the initial height of the projectiled: the total horizontal distance travelled by the projectileWhen neglecting air resistance, the range of a projectile will beIf (y0) is taken to be zero, meaning the object is being launched on flat ground, the range of the projectile will then simplify toso to increase the range θ shoud vary from 0 to 45 and after 45 it starts decreasing.
What was the initial speed, v0, of the bullet?
To determine the initial speed, v0, of the bullet, you need to use the given information and relevant equations from physics, such as the equation for projectile motion. By analyzing the trajectory of the bullet and considering factors like distance traveled and time taken, you can calculate the initial speed of the bullet.
In 0.5 seconds a projectile goes from 0 to 300 ms. what is the acceleration of the projectile?
The acceleration of the projectile can be calculated using the formula: acceleration = change in velocity / time taken. In this case, the change in velocity is 300 m/s (final velocity) - 0 m/s (initial velocity) = 300 m/s. The time taken is 0.5 seconds. Therefore, the acceleration would be 300 m/s / 0.5 s = 600 m/s².
When is the acceleration taken as negative?
Acceleration is taken as negative when an object is decelerating or slowing down. In this case, the acceleration vector points in the direction opposite to the velocity.
