Q. A 15 kg box is pushed with a force of 30 N. What is the box's acceleration?
A.
1 m/s²
B.
2 m/s²
C.
3 m/s²
D.
4 m/s²
Solution
Using F = ma, we find acceleration: a = F/m = 30 N / 15 kg = 2 m/s².
Q. Which of the following is an example of Newton's first law?
A.
A ball rolling on a flat surface eventually stops.
B.
A rocket launches into space.
C.
A car accelerates when the gas pedal is pressed.
D.
A person pushes a wall.
Solution
Newton's first law states that an object will remain at rest or in uniform motion unless acted upon by a net external force. The ball rolling and eventually stopping is an example.
Correct Answer:
A
— A ball rolling on a flat surface eventually stops.
