$\begingroup$ If an object is accelerating that means someone applying force on the object, And if there is no force on the object then the object moves with constant velocity. now if the object is moving with a constant velocity and it strike me and object stop moving that mean I have applied a force on the object and the ball will also apply ...

Sep 27, 2017 · Acceleration and velocity. Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate.
Suppose a person is applying force 5 Newton in -> direction. Friction is 5 Newton in <- direction. (( The person had to start moving box by applying a slightly larger force: say 5.001 Newton at time=0. so that an instantaneous acceleration increases the velocity to some constant value. )) now lets say velocity is 1 m/s.
Oct 21, 2024 · Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.

An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.The acceleration of an object depends on the mass of the object and the amount of force applied.Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first.Examples of inertia involving aerodynamics:
1. The motion of an airplane when a pilot changes the throttle setting of an engine. 2. The motion of a ball falling down through the atmosphere. 3. A model rocket being launched up into the atmosphere. 4. The motion of a kite when the wind changes.
Example of force involving aerodynamics:
1. An aircraft’s motion resulting from aerodynamic forces, aircraft weight, and thrust.
Examples of action and reaction involving aerodynamics:
1. The motion of lift from an airfoil, the air is deflected downward by the airfoil’s action, and in reaction, the wing is pushed upward. 2. The motion of a spinning ball, the air is deflected to one side, and the ball reacts by moving in the opposite direction. 3. The motion of a jet engine produces thrust and hot exhaust gases flow out the back of the engine, and a thrusting force is produced in the opposite direction.
If a body has a non-zero, but constant, velocity then we know that the total of all the forces applied to it is zero (from Newton's Laws). We also know that is has non-zero "momentum", and when it collides with another object some (or all) of that momentum can be transferred to the other object.
Newton's First Law can be used to explain the movement of objects travelling with uniform motion (constant velocity). For example, when a car travels at a constant speed, the driving force from ...
