1) An object at rest has zero acceleration. 2) The distance-time graph of a body in uniform motion is parabola. 3) The slope of a velocity-time graph represents acceleration. 4) Objects slowing down are experiencing positive acceleration
It has zero acceleration since the change in velocity is also zero. An object can also have zero acceleration if the velocity is constant (zero change in velocity).
2) The distance-time graph of a body in uniform motion is parabola.
Answer:
TRUE
The curve resembles the parabola
3) The slope of a velocity-time graph represents acceleration.
Answer:
TRUE
Acceleration is the change in velocity over time or the change in time.
4) Objects slowing down are experiencing positive acceleration
Answer:
FALSE
Object slowing down have a negative acceleration or decelerating. Object speeding up have positive acceleration or accelerating.
