• speed

• time

Which refers to a particular way in which someone or something is located, placed or arranged?

• distance

• position

• speed

• time

Which of the following measures the length or the amount of space between two points or places?

• distance

• speed

• time

• velocity

Which of the following will be observed in a line graph between distance vs. time?

• acceleration

• speed

• displacement

• velocity

What happens to the graph if there is zero acceleration?

• the graph will be diagonal to the right

• the graph will be diagonal to the left

• the graph will form letter w

• the graph will have horizontal line

Who proposed the law of gravity and 3 laws of motion (Inertia)?

• Aristotle

• John Joseph Dalton

• Albert Einstein

• Isaac Newton

What does Newton's First Law of Motion state about the motion of objects?

• objects will accelerate when no force is applied

• objects will remain in uniform motion unless acted upon by an external force

• objects will come to rest without any external influence.

• objects require continuous force to maintain motion

Which of the following statements aligns with the physics definition of acceleration?

• An object moving at a constant speed in a circular path is accelerating.

• An object moving at a constant speed in a straight line is accelerating

• An object at rest is accelerating.

• An object moving at a constant velocity is not accelerating

If a car's speed decreases as it comes to a stop, what can be said about its acceleration?

• The car has zero acceleration.

• The car has positive acceleration.

• The car has negative acceleration.

• The car's acceleration cannot be determined without more information.

Which of the following scenarios describes acceleration in physics?

• car traveling at a constant

• person walking at a steady pace

• ball thrown upward, slowing down as it rises

• plane cruising at a constant altitude and speed
