Question

According to Newton’s third
law of motion, which
statement is always correct?
If a moving object hits
another object, then
the second object will
push back.
If two moving objects
collide, then both will
stop moving.
If a moving object hits
another object, then
the second object will
start moving.
If two moving objects
collide, then they will
bounce off each other.

Answer 1

According to Newton's third law of motion, the correct statement is:

**If a moving object hits another object, then the second object will push back.**

This law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on a second object, the second object exerts a force of equal magnitude and opposite direction back on the first object.

The other statements are not necessarily true:

- **If two moving objects collide, then both will stop moving.** (Not true; they may both continue moving, bounce off, or one may stop while the other continues.)
- **If a moving object hits another object, then the second object will start moving.** (Not necessarily true; it depends on the masses and velocities involved.)
- **If two moving objects collide, then they will bounce off each other.** (Not true; they may stick together, crash, or deform upon collision instead.)
