What does a stationary object do to a moving object?
Total momentum is always conserved between any two objects involved in a collision. The stationary object encounters the greater collision force. A moving object collides with a stationary object; the stationary object has significantly less mass. The stationary object encounters the greater momentum change.
What is the difference between stationary object and moving object?
If the resultant force on an object is zero, this means: a stationary object stays stationary. a moving object continues to move at the same velocity (at the same speed and in the same direction …
What can a force do to stationary and moving objects?
Force can cause a stationary object to start moving or a moving object to change its speed or direction or both. A change in the speed or direction of an object is called acceleration.
What two forces are acting upon a stationary object?
The primary forces acting on anything are gravitation and electromagnetic, as well as frictional forces which have to be overcome to initiate motion.
How do you know if an object is stationary?
A particle moving in a straight line is stationary when its velocity is zero, that is, dxdt=0. This is the origin of the term ‘stationary point’ introduced in the module Applications of differentiation.
Are there any forces on a stationary object?
In the case of strong materials like concrete or steel table frames this compression is usually very small and not observable unless the applied force is very large. Stationary objects have forces on them. All objects undergo some squashing or stretching when a force is applied to them.
When does a moving object collide with a stationary object of?
The laws of conservation of kinetic energy and linear momentum allow to calculate exactly the velocities V 1 and V 2 of both objects after an elastic collision: The other algebraically correct solution V 1 = 0 and V 2 = V should be discarded since physically it means that moving object goes through the stationary.
What happens when one object pushes on another object?
When one object pushes on another, the surface of the second object is squashed. Because it is squashed the second object pushes back on the first. For example, a chair bends as a person sits on it and because it is bent, it pushes back up on the person.
How is the earth moving relative to a spaceship?
If the person on the Earth sees the spaceship moving at 0.95c, the observer on the spaceship agrees that the Earth is moving at 0.95c with respect to the spaceship (and because the other planet is not moving relative to the Earth), everyone’s in agreement that the relative velocity between the spaceship and planet is 0.95c.
