True
The two forces acting on a projectile in motion are gravity, which always acts downward, and air resistance, which opposes the projectile's motion through the air. Gravity causes the projectile to follow a curved path, while air resistance slows down its movement.
No, a projectile is not always in free-fall. A projectile is any object that is thrown or launched into the air and is affected by gravity. While a projectile is influenced by gravity and follows a curved path, it may not necessarily be in free-fall if other forces are acting on it, such as air resistance or propulsion.
In two-dimensional motion that is not projectile motion, the object may have acceleration even if it is not accelerating overall. This is because the object's velocity can change direction in two dimensions without necessarily changing its magnitude, leading to acceleration along curved paths. Projectile motion, on the other hand, involves acceleration only in the vertical direction due to gravity while the horizontal velocity remains constant.
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.
The force of gravity always pulls downward on objects. It is a natural phenomenon by which all objects with mass are brought towards one another.

Osmosis always involves the movement of water. During osmosis water will move in and out of the cell or membrane.
Yes,it's always downward sloping

In American Sign Language (ASL), the sign for 'always' involves creating two flat hands with palms facing downward and moving them in a circular motion in front of your body. This movement signifies the continuous or constant nature of 'always.'
Assuming negligible air resistance, the acceleration of a projectile near the Earth's surface is always the gravitational 9.81 m/sec/sec downwards, regardless of where in the trajectory the projectile is.

bullet starter
Since I have read that the path of a projectile is always a parabola, I must say no. The parabolic shape of a projectile's path results from the combination of the force and direction with which it is launched and its weight.A ball rolling down a slope, is not Projectile Motion. While a cannon ball can be used to be a projectile, as far as Physics goes, that is not how it is operating at the moment (rolling down a slope).
Weight always acts in the downward direction due to gravity.
