In which situation does the reactive force between two colliding objects cause a physical change? (1 point)
the exhaust from a rocket thrusting the rocket away from the ground
two bumper cars at an amusement park colliding, causing both cars to change direction
a baseball player swinging a bat and hitting a baseball, causing the bat to shatter
a swing hitting another swing, causing the second swing to move away
Two bumper cars at an amusement park colliding, causing both cars to change direction.
The situation in which the reactive force between two colliding objects causes a physical change is when two bumper cars at an amusement park collide, causing both cars to change direction.
The situation in which the reactive force between two colliding objects causes a physical change is when two bumper cars at an amusement park collide, causing both cars to change direction.
To understand why this is the correct situation, let's break down the options:
1. The exhaust from a rocket thrusting the rocket away from the ground: In this case, the reactive force between the rocket and the exhaust does cause a physical change (the rocket being propelled away), but it does not involve two colliding objects.
2. A baseball player swinging a bat and hitting a baseball, causing the bat to shatter: While this scenario involves two objects colliding (the bat and the ball), the reactive force exerted by the ball causes the bat to shatter, not the other way around. So, it doesn't fit the criteria.
3. A swing hitting another swing, causing the second swing to move away: In this situation, two swings collide, and the reactive force between them causes the second swing to move away. However, the reactive force does not cause a physical change in either swing; it simply results in the motion of the second swing.
Therefore, the correct situation where the reactive force between two colliding objects causes a physical change is two bumper cars colliding at an amusement park, causing both cars to change direction.
