If the net force acting on a sliding block is somehow tripled, what happens to the acceleration? Surprisingly, the answer is that it remains unchanged. The reason for this is that the net force doesn’t really affect the acceleration in a real-world situation; it only affects how quickly the block moves.
The net force F is given by the sum of all the forces acting on the block. These forces include the weight W and friction fr. The frictional force is given by the product of normal reaction coefficient n and pressure p. Since the net force is 3 times as large, we know that the acceleration will be 3 times as large.
What is the acceleration due to gravity?
The acceleration due to gravity is the rate of change in an object’s velocity vector with respect to time. This acceleration is caused by the force of gravity, which is exerted by a larger object on a smaller object. The magnitude of this acceleration depends on the mass of the objects involved and the distance between them.
What is the difference between a force and a push or a pull?
A force is an action or condition that causes a change of motion, while a push or a pull is an action or condition that changes the position of an object.
For example: If you throw a ball in the air, then it’s the force that makes the ball move upward. But if you pull the string of a kite, then it’s the pull that makes the kite rise.
What is the difference between a force and a mass?
A force is a push or pulls applied to something which causes that object to move. An object under the influence of a force does not move unless acted upon by some outside force (like gravity). An object can exert a force on another object, and so can a person. For example, when you throw a ball at another person, the person being thrown at must exert a force on the ball. In physics, the quantity of the force exerted is called the **force**, and the resulting motion of the object is called the **acceleration**. The magnitude of the force determines the direction and the speed of the motion, while the strength of the force determines the degree to which the object is moved.
Force is the pressure of one body on another. It is measured in newtons and is sometimes referred to as “pressure.” The SI unit of force is the newton, abbreviated N, which is equal to the gravitational constant times the weight of the body involved in the force.
Mass is the amount of matter in an object. If you have a cup of coffee, the amount of matter in the coffee is its mass. Mass is measured in kilograms.
You can apply forces to objects, but you cannot apply masses to objects. If you hold a massless ball, you can’t accelerate it. But you can exert a force on a massless ball. This is what you mean by “lift a person off the ground.”
You can accelerate a mass, but you can’t exert force on a mass.
