It's because you can't create a force with your muscles that exceeds the
forces of gravity attracting the box and the Earth toward each other.
True
true
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.
the force that opposes the motion of two touching surfaces is velocity.
There are many types of forces that oppose motion such as friction, drag and most universal, gravity.
Gravity. The inertia of an object will keep it moving until an opposing force stops it.Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
Force of friction
This is true
Yes, the upward force that opposes the force of gravity is called the normal force. It acts perpendicular to the surface that an object is resting on, preventing it from falling through.
Well, it's true that the gravitational force acting on the box acts in the direction opposite to the direction of your lifting force, but there's nothing malicious or contrary about it. In fact, the gravitational force was there before you came on the scene, and as you lined up your lift, it was you who decided to oppose it.
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.
Any force with an upward vertical component does.
Other common names for the normal force that opposes gravity are support force, contact force, and reaction force.
The force that opposes the effort force is called the resistance force. It acts in the opposite direction to the effort force and may come from factors like friction or gravity.
the force that opposes the motion of two touching surfaces is velocity.
Gravity pushes in, fusion pushes out.
The force of gravity keep a bycicle on the ground.
The buoyant force acts in the opposite direction to gravity, which is upwards. It is the upward force exerted by a fluid on an object submerged in it that opposes the weight of the object.
gravity means the force that keeps the force up on the ground and the grip on the ground are ruff
