any change NOT involving a change in the substances chemical identity- type of matter is still the same
for ex. you cold change the texture, volume, shape, mass, size, weight, color, density, or odor.
More scientifically, it's a change that doesn't involve altering the chemical makeup of an object.
I'll give a few examples.
Take a glass window and break it. Now, instead of one pane of glass, you have many small shards of glass- but they're still glass!
Take water and freeze it. Ice is simply water in a different phase, it's still molecules of h2o, so chemically it is the same.
Take a piece of copper wire and bend it. The physical properties of the wire are now different- it has a bend in it. But it's still copper!
An example of a change that's not physical, but chemical, would be rusting iron. When iron rusts it becomes chemically different, a compound called iron oxide (Fe -> FeO).
Physical change is a change which takes place without any process of mixing of chemicals. It is a process of change in matter by manual method. If matchstick is burnt the burnt part cannot be regained. This is called chemical change.If the paper is crushed it can be regained to its original shape. this is called physical change.
so basically a pyhsical change is any change NOT involving a change in the substances chemical identity- type of matter is still the same
The change in position of an object compared to a reference point(another object) is called motion.
A change in an objects position relative to a reference point is called motion.
motion =)
the answer is motionAn angle.DisplacementMotion is a change in the position of an object in relation to a reference point.
It is the process of a change in position relative to some fixed point of reference.
The change in position of an object compared to a reference point(another object) is called motion.
A change in an object's position relative to a reference point is called motion.
Displacement is the term used to describe the change in position of an object when compared to a reference point. It is a vector quantity that includes both the distance and the direction of the movement.
The change in position of a point in reference to a previous position is called displacement.
A change in an objects position relative to a reference point is called motion.
A change in an objects position relative to a reference point is called motion.
Actually, a change in the position of an object when compared to a reference point is defined as displacement. Speed, on the other hand, is the rate at which an object covers distance over a period of time.
A change in position relative to a reference point is called displacement. Displacement is a vector quantity that describes the change in position of an object in terms of distance and direction from a starting point to an ending point.
A change of position to a reference point is called displacement. Displacement is a vector quantity that describes the overall change in position of an object relative to its starting point. It includes both distance and direction traveled.
A change in an objects position relative to a reference point is called motion.
When an object's position changes, it is referred to as motion. Motion is the change in position of an object over time relative to a reference point.
