Of course there is. Gravity effects everything on or near the Earth. If it didn't then whenever you left the surface of the Earth, you'd just float away into space.
weight, The weight of an object is the force of gravity acting on it.
Since the passenger is also traveling in a straight line at constant speed the net force on him is zero.
I have no idea what you mean - the force of gravity acts everywhere.
The force exerted by the earth towards itself,known as the gravitational force is called that gravity is acting on you.
Gravity is what keeps the planets going in their orbits. If gravity just stopped, then the planets would go flying in a straight line tangent to their orbit.
g force
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
The force acting upon it is energy.
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
The main forces acting on a bird in flight are gravity, drag caused by wind resistance as it moves through the air, and lift produced by the motion of its wings that keep it up. A bird on the ground is mostly just affected by gravity.
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
The force of gravity on an object is called its weight.Note that mass is what CAUSES this force of gravity.
