Motion that is under the influence of gravity alone is called?
Free fall is the term in Newtonian physics used to describe the motion of an object under the influence of gravity alone. Such an object moves along a geodesic. One example of an object always in free fall is Earth's moon.
What is the difference between free fall and projectile motion?
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.
Is gravity in the only force acting on an object the object is in a what?
When an object is in free fall, gravity is the only force acting on it. This occurs when the object is falling under the influence of gravity alone, with no other forces like air resistance or drag affecting its motion.
How does the downward component of the motion of a projectile compare to the motion of free fall?
The downward component of the motion of a projectile is influenced by the initial velocity and angle of launch, resulting in a curved path known as a projectile motion. In contrast, free fall refers to the vertical motion of an object under the influence of gravity alone, where the acceleration is constant and the path is straight.
What kinds of motion required no forces?
An object in uniform motion will continue moving at a constant velocity without any net force acting on it. Additionally, an object in free fall will move under the influence of gravity alone, and does not require any other forces to be in motion.

Why projectile motion similar to free falling motion?
Projectile motion is similar to free falling motion because both involve objects moving under the influence of gravity alone. In both cases, the only force acting on the object is gravity, causing it to accelerate downward at a constant rate (9.81 m/s^2). This results in a parabolic trajectory for projectiles and straight vertical motion for free falling objects.
An air hockey puck bouncing off the sides of the table is an example of projectile motion.?
No. The definition of projectile motion is an object dropped launched into the air, which is acted upon by gravity. (For the basic forms of the motion, air resistance is ignored.)
How does air effect gravity?
Air does not affect gravity directly, as gravity is a force of attraction between objects with mass. However, air resistance can have an impact on the motion of objects falling through the air, as it opposes the force of gravity and can slow down the object's descent.
What is required for an object to be considered in free fall?
An object is considered to be in free fall when it is only under the influence of gravity with no other forces acting upon it, such as air resistance or buoyancy. This means the object is accelerating due to gravity alone.
Is it possible to lift a piece of paper by looking at it?
No, looking at a piece of paper cannot physically lift it. Gravity acts as a force that pulls objects downward, so visual observation alone cannot counteract gravity's influence on the paper.
Erosion that occurs when gravity alone causes rock or sediment to move down a slope?
The type of erosion that occurs when gravity alone causes rock or sediment to move down a slope is called mass movement. The types of mass movement are creep, slump, rock slides, and mudflows.
Which erosional force acts alone to produce avalanches and landslides?
Gravity acts alone to produce avalanches and landslides. When the force of gravity exceeds the strength of the material holding it in place on a slope, the material will move downhill in the form of an avalanche or landslide.
