Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. Earth's gravity is what keeps you on the ground and what makes things fall.
Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.
Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.
Gravity is also what keeps the moon in orbit around Earth. And the reason you always land back on your feet is because of gravity too!
What else can I help you with?
Which of the following can cause a change in the motion of an object?
Forces such as gravity, friction, and applied forces can cause a change in the motion of an object. Other factors such as air resistance or buoyancy can also influence the motion of an 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.
What is motion that is under the influence of gravity alone called?
Motion under the influence of gravity alone is called free fall. In free fall, an object is only acted upon by the force of gravity, causing it to accelerate towards the Earth at a constant rate.
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 only reguriment for an object to be in projectile motion?
The only requirement for an object to be in projectile motion is that it must be launched or thrown into the air with an initial velocity. Once in motion, the object will follow a curved path under the influence of gravity, with no additional propulsion.

Which term describes motion without air resistance to gravity?
Projectile motion describes the motion of an object in the absence of air resistance and under the influence of gravity. This type of motion involves the object traveling in a curved path due to the combined effects of its initial velocity and gravitational force.
What does NOT exhibit parabolic motion?
Objects moving in a straight line or in circular motion do not exhibit parabolic motion. Parabolic motion is characterized by an object following a symmetrical path under the influence of gravity.
What is physics projectile motion?
Physics projectile motion is the motion of an object that is projected into the air and then moves under the influence of gravity. The object follows a curved path known as a trajectory, exhibiting both horizontal and vertical motion. The key factors affecting projectile motion are the initial velocity of the object, the angle at which it is launched, and the force of gravity.
What are the key principles governing the trajectory of an object in free fall under the influence of gravity, known as projectile motion?
The key principles governing the trajectory of an object in free fall under the influence of gravity, known as projectile motion, include the initial velocity, angle of launch, and gravitational force acting on the object. These factors determine the path the object will follow as it moves through the air.
What do motion depend on?
There are three things that motion depends upon. The first is the mass of the object that is to be set into motion. The second is the strength of the friction that is going up against the object. The third is the strength of the gravity that is pulling upon the object.
Is a free fall a vertical component of motion?
Yes, free fall refers to the motion of an object falling solely under the influence of gravity, without any other forces acting upon it. The vertical component of motion in a free fall is the object's downward movement due to gravity.
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.
