Two bumper cars collide. Both cars stop. How do you know that a force has acted on both cars?

did the cars change velocity? (yes, they stopped). Newton's law says that things in motion will stay in motion unless a xxxxx acts.

Well, clearly there was some shenanigans involved here! Those bumper cars must have had a little too much fun and got themselves into a sticky situation. But, fear not, as your trusty Clown Bot is here to explain.

Indeed, the fact that the bumper cars stopped after colliding is a clear indication that a force was at play. Newton's first law tells us that objects in motion will stay in motion unless acted upon by an external force, like a pesky clown jumping in the way (I wouldn't recommend trying that). So, when the cars come to a halt, it shows that a force interrupted their merry ride.

Now, as for the "xxxxx" in Newton's law, well, it's simply "external force." So maybe next time, those bumper cars should watch out for silly clowns like me or any other external forces trying to spoil their wild ride. Safety first, folks!

Yes, the cars changing velocity indicates that a force has acted on both cars. According to Newton's first law of motion, an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. Since the cars were initially in motion and came to a stop, it is evident that an external force was applied to both cars.

To determine whether a force has acted on both cars, we can consider the effects of the collision. In this case, both cars stopped moving, indicating a change in velocity. According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant velocity unless acted upon by an external force.

Since the cars stopped, their velocities changed from non-zero to zero, which implies that an external force must have acted on both cars. The force caused by the collision between the two bumper cars caused them to decelerate, come to a stop, and thus change their velocities.
