Gravity
Gravity -Apex:)
The correct answer is gravity
Gravity must be the only force acting on the object.
For an object to be in projectile motion, it must be subject to the force of gravity. This force causes the object to accelerate downward while in flight, leading to the curved trajectory characteristic of projectile motion. Other forces like air resistance may also affect the object's motion, but gravity is the primary force at play.
The horizontal component of projectile motion is not influenced by gravity. This means that the object will continue to move horizontally at a constant velocity, regardless of gravity acting on it.
The only active force acting on a projectile is gravity. Once the object is released, the only force affecting its motion is the force of gravity pulling it downward.
The two forces that affect the motion of a projectile are gravity and air resistance. Gravity acts to pull the object downward, influencing its vertical motion, while air resistance affects the projectile's horizontal motion by slowing it down as it travels through the air.
The motion of an object thrown at an angle is projectile motion. This type of motion involves the object following a curved path due to a combination of its initial velocity and the force of gravity acting upon it. The object moves both horizontally and vertically as it travels through the air.
Uniform projectile motion is caused by the combination of an initial velocity and the force of gravity acting on the object. As long as there are no other external forces acting on the object, such as air resistance or friction, the object will follow a predictable parabolic path.
Yes. Gravity acts downward on a projectile. That is why on Earth, objects eventually start to come down after throwing them, without the force of gravity acting downward the object would continue in a straight line forever.
Free fall is the motion of an object falling under the influence of gravity alone, without any initial horizontal velocity. Projectile motion, on the other hand, involves both horizontal and vertical motion, with an initial horizontal velocity and the force of gravity acting on the object.
