What forces besides gravity acts on a projectile?

What forces besides gravity acts on a projectile?

projectile motion, the motion of a falling object (projectile) after it is given an initial forward velocity. Air resistance and gravity are the only forces acting on a projectile.

What is a force that causes objects to gain momentum?

True. A force that causes objects to gain momentum is friction.

What force opposes your push?

The force that acts against your pushing force is called friction. is a force that resists the motion between two surfaces in contact. When you try to slide two surfaces across each other, the force of friction resists the sliding motion.

Is gravity not a force?

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line.

Why is momentum not a force?

Momentum is amount of motion in a moving body, whereas force is an action of push or pull. Force changes momentum of a body. Force does not change for constant acceleration whereas momentum changes. Momentum increases with time for an applied force.

Is gravity or weight a force?

Weight W is just another word for the force of gravity F g F_g Fg​F, start subscript, g, end subscript. Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth.

What are the 3 types of forces?

Types of Action at a distance forces are: Gravitational force, Electrical force and Magnetic forces.

What is the difference between momentum and gravity?

Gravity – we all know, but the other behaves very differently. With momentum, you can overcome gravity itself. Gravity is the most well-known phenomenon on this earth. Everything is subject to it. Whether it be walking up and down hills or falling down the stairs or even kneeling down and standing back up again, gravity pulls us to the ground.

What is the difference between inertia and momentum?

Inertia is a characteristic all objects have, the characteristic of resisting change in motion, based solely on the object’s mass. Momentum is a force when an object is moving in a direction, based on mass AND velocity. Because of this, it is your own momentum that is pushing you around.

Why is the force of gravity the weakest at the equator?

The force of gravity is weakest at the equator because of the centrifugal force caused by the Earth’s rotation and because points on the equator are furthest from the center of the Earth. The force of gravity varies with latitude and increases from about 9.780 m/s 2 at the Equator to about 9.832 m/s 2 at the poles.

What is the mass of a body with constant gravitational force?

Under an assumption of constant gravitational attraction, Newton’s law of universal gravitation simplifies to F = mg, where m is the mass of the body and g is a constant vector with an average magnitude of 9.81 m/s2 on Earth.
