relativity
Force is directly proportional to the mass of the object which in turn depends on the density and volume of the object.It also matters whether the body is aldready at motion or not.
it depends on the reference points, that is form where the object is viewed...when sun is viewed form earth, it moving...but earth is also moving...when the rotation of the earth is stopped, then the sun is at a constant position...thereforean object position relative to another object is changingonly when the reference point changes..
Inertia is the resistance of a object to change in its motion
an object in motion will stay in motion unless acted upon by another force
Inertia is dependent on the mass of the object being considered, and sometimes by its momentum - depending on how we are using the term. Recall that inertia is the resistance of a body to a change in motion. (A body at rest tends to remain at rest unless acted on by an outside force. And, a body in motion tends to remain in motion unless acted on by an outside force.) We think of something massive as resistive to being moved. That's inertia. But it's not moving. If that same massive body is rolling, it will have a lot of momentum, and it will take a great deal of force to slow and stop it. In the first case, the object has no velocity, and will have no momentum. In the second case, it's moving, and it will have momentum.
By observing the object
True. The motion of an object can be measured by observing its position change over time. This can be done by using tools such as cameras, sensors, or motion detectors to track the movement of the object.
reference point. By observing the motion of an object in relation to a reference point that seems stationary, you can detect the motion of the other object. This method is commonly used in physics and everyday situations to analyze motion.
An object is in motion if its position changes relative to a reference point. This can be observed by observing the object's change in position over time or by tracking its movement visually or with instruments.
Kinetic energy is the energy caused by the motion of an object.
Objects in motion have kinetic energy and objects at rest have potential energy. Whether or not the object in motion has more energy than the same object at rest or vice versa depends on specific circumstances. It depends on the speed of the object in motion.
Reference point
The motion of an object can be inferred by analyzing its changes in position over time. This is typically done by measuring the object's displacement or velocity using tools like a motion sensor, camera, or tracking software. By observing how the object's position changes relative to a reference point or frame of reference, we can determine the type and direction of its motion.
You can determine the relative motion of another object by observing its motion in relation to a fixed reference point or another object. This can involve comparing the speed, direction, and distance of the object relative to yourself or another point of reference. Calculating the velocity or acceleration of both objects can also help determine their relative motion.
A motion graph provides a visual representation of an object's motion over time, making it easier to interpret and analyze compared to text or numerical data. It allows for observing trends, patterns, and changes in motion with a single glance, aiding in understanding the dynamics of the object's movement.
Parallax is the apparent shift in position of an object when viewed from different angles or positions. This phenomenon is often used in astronomy to measure distances to nearby stars by observing their slight change in position relative to more distant stars as the Earth moves around the Sun.
The direction of motion can be determined by observing the change in position of an object over time. If the position is increasing, the object is moving in the positive direction; if it is decreasing, it is moving in the negative direction. Additionally, the sign of the velocity can indicate the direction of motion: positive for forward motion and negative for backward motion.
