Question 5 • Physics in the Universe

According to Newton’s first law of motion, what will an object in motion do when no external force acts on it?

Answer
A
move at the same velocity
B
come to a stop
C
speed up
D
change direction

Explanation

Newton’s first law says that an object keeps its state of motion unless an external force acts on it. So an object already in motion continues at the same velocity, meaning its speed and direction remain unchanged. The correct choice is “move at the same velocity.”
