What is the force that opposes gravity?
Normal force always acts perpendicular to the contact surface. It can act counter to gravity or to any other force that pushes an object against a surface. Think of normal force as the force that keeps a surface solid; without normal force, an object would pass right through a surface.
What force opposes gravity on falling objects?
Science–Ch. 4
| A | B |
|---|---|
| ____ is the only downward force acting on a freely falling object. | gravity |
| What opposes acceleration of a falling object due to gravity? | air resistance |
| According to Newton’s second law, acceleration depends on the size of the force and the ______ of an object. | mass |
What force opposes gravity when an object is on a surface?
The normal force is the force that surfaces exert to prevent solid objects from passing through each other. Normal force is a contact force.
Which force opposes the movement of an object?
FRICTION
FRICTION: Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.
What’s the force called that opposes motion?
Friction
Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.
What is the force that causes objects to fall on the ground?
The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall.
What forces oppose each other?
Friction is a force that opposes the motion or tendency toward motion of two objects that are in contact with one another.
What force opposes the motion of the object even though there is an external force?
Friction is the force between an object in motion and the surface on which it moves. Friction is the external force that acts on objects and causes them to slow down when no other external force acts upon them.
What kind of force opposes the motion of the feather?
What is the difference between gravity and applied force?
If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person. The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object.
What is the direction of force of gravity on Earth?
All objects upon earth experience a force of gravity that is directed “downward” towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found by the equation:
Does friction always oppose the motion of an object?
Though it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion.
Why do stars have a gravitational force?
The answer is — because gravity holds the pieces of the star together. Each atom in the star attracts every other atom in the star with a force which depends on the masses of the atoms and on the distance between them.
