Accurate but not precise
Neither precise nor accurate
Angela measured the melting point of an unknown substance. She conducted 3 trials and her instrument read its temperature to 44.15⁰C repeatedly before the substance melt. She found out that the substance is made up of phosphorus (melting point = 44.15⁰C). How do you describe the measurement obtained by Angela?

Zero slope
What would be the possible interpretation of this velocity vs. time graph?
The object is at rest.
The object is at constant velocity
The object is at constant acceleration
The object is at changing velocity
In order to have a constant velocity, which of the following must be observed?
An object must have a constant speed in a constant direction.
An object must have a constant speed in all directions.
An object must have a non-uniform motion in one direction.
An object must have a non-uniform motion in all directions.
Which of the following statements is TRUE about motion in one-dimension?
If the speed is constant, the velocity is constant.
Non constant velocity means constant acceleration.
Acceleration is always constant if you have a non-zero velocity.
