Force is the one and only means of bringing about a change in motion.
The motion of an object is directly related to the amount of force applied to it. The greater the force applied, the more acceleration the object will experience, leading to a change in its motion. The relationship is described by Newton's second law of motion, which states that force equals mass times acceleration.
Force is any interaction that, when unopposed, will change the motion of an object. Force can cause an object to accelerate, decelerate, stop, or change direction. Essentially, force and motion are directly related, as force is what causes changes in the motion of an object.
Force=mass*acceleration
Frictional
In order to create force, you have to create motion. So if you were to push on a box or pull your child away from the street, you would be creating a motion and force.
Newton's second law of motion states that an object's acceleration is directly related to the net force applied and inversely related to the mass of the object.
Net force is the overall force acting on an object, causing it to accelerate or change its state of motion. Inertia is the resistance of an object to changes in its state of motion. The net force acting on an object is directly related to the object's inertia; the greater the net force, the greater the acceleration or change in motion, and the object's inertia will determine how easily it can be accelerated or changed.
I can help you understand concepts related to force and motion if you have specific questions. Could you provide more details on what you'd like to know?
Friction always acts opposite to the direction of motion.
The concept related to the amount of force needed to change an object's motion is inertia. Inertia is the tendency of an object to resist changes in its velocity. Objects with more mass have greater inertia and require more force to change their motion.
Gravitational force is a naturally occurring force related to two bodies in motion. It is the attraction between objects with mass and is responsible for keeping planets in orbit around the sun and objects on Earth's surface.
The work done by a constant force on an object affects its motion by changing its speed or direction. If the force is in the same direction as the object's motion, it can increase its speed. If the force is in the opposite direction, it can slow down or stop the object. The work done by the force can also change the object's kinetic energy, which is related to its motion.
