What happens when three blocks are placed on a frictionless horizontal surface?
When three blocks are placed on a frictionless horizontal surface, they will remain stationary unless an external force is applied to them. If a force is applied to one of the blocks, it will move in the direction of the force, while the other blocks will remain stationary due to the absence of friction.
What is normal force?
Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.
Which direction will the load move if the force applied to the rope is greater than the force of gravity on the load?
I assume this is not a trick question of like the rope is not taut. If the rope is taut, the load will move to the combined force of the applied force and gravity, in the vector sense. In the simple case of the applied force being directly opposite to gravity, the load will rise straight up from the ground. If the applied force is perpendicular to gravity (that is, horizontal), the load will drop to the ground at an angle, depending on the sum of the two force vectors.
Does the acceleration remain constant if the applied force was increasing?
No. Acceleration is proportional to the applied force.
What would happen to an object when normal force and force of gravity is applied?
When a normal force and force of gravity act on an object, the object will either remain stationary if the forces are balanced, or accelerate in the direction of the unbalanced force if there is a net force acting on it. The normal force is perpendicular to the surface the object is in contact with, while the force of gravity acts vertically downward towards the center of the Earth.
What is the torque due to gravity on the disk?
The torque due to gravity on the disk is the force of gravity multiplied by the distance from the center of the disk to where the force is applied.
When a force is applied that moves an object in the direction of the applied force is gravity done?
Gravity is indeed a force, but only one out of many. magnetic, frictional, mechanical ... . When an ordinary force applied to an object, (me pushing my wheelbarrow) this would not be considered as being affected by gravity.
Why a man lifting a box to be placed on a table is work?
In physics, work is performed when a force is applied to an object and causes it to move in the direction of the force. In this scenario, the man lifting the box is applying a force to move the box upwards against the force of gravity. The work done is equal to the force applied multiplied by the distance the box is lifted.
What would be the applied force of a free falling object?
gravity
What is the force applied by the machine to overcome resistance due to gravity or friction?
The force applied by a machine to overcome resistance due to gravity or friction is known as the applied force. Applied force is the amount of force needed to move an object against a resisting force, such as the force of gravity or friction. This force is usually measured in Newtons (N). When an object is stationary, the applied force is equal to the resisting force. When an object is moving, the applied force must be greater than the resisting force in order to maintain the object's motion. If the applied force is too small, the object will slow down and eventually stop. If the applied force is too great, the object may accelerate or move too quickly.In order to determine the applied force, the resisting force must first be calculated. This can be done by multiplying the mass of the object by the acceleration due to gravity. The resisting force due to friction can be calculated by multiplying the normal force of the object by the coefficient of friction between the object and the surface it is in contact with.
What do we call the amount of force placed on something?
The amount of force placed on something is called pressure. It is defined as the force applied per unit area.
For motion to occur?
For motion to occur, an object must experience a force that causes it to accelerate and move. This force can come from sources like gravity, friction, or applied forces. In the absence of a force, an object will remain stationary or in constant motion.
