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
In science a physical change is a change which is reversible, no new substance is made.
Example: an ice cube in the sun goes from solid to liquid then evapourates and turns into gas.
A change in position would be motion.
(Motion) is the answer for A+
A change in an objects position relative to a reference point is called motion.
Displacement refers to the change in the position of an object. This measurement includes both the magnitude as well as the direction.
A change in position is called displacement.
This is referred to as motion.
Displacement.
Acceleration
Velocity.
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.
false
Motion
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.
movement or motion
if a body do not change its position with time as compared to a reference point then the body is said to be in rest
motion =)
A change in an objects position relative to a reference point is called motion.
When its position changes with respect to a point of reference.
No, this would be "displacement" or "motion." Speed is the non-directional scalar quantity (magnitude) for the rate of positional change.
