A scientist wanted to move a golf ball and a bowling ball to both reach 15 mph. What would the scientist have to do differently for the bowling ball than the golf ball to reach his goal?
To move both the golf ball and the bowling ball to reach 15 mph, the scientist would have to do the following differently for the bowling ball:
1. Apply more force: The bowling ball is heavier than the golf ball, so it would require more force to accelerate it to 15 mph compared to the golf ball.
2. Apply the force for a longer duration: Since the bowling ball is larger and heavier, it would take more time to accelerate it to the desired speed. The scientist would need to apply the force for a longer duration to allow the bowling ball to reach 15 mph.
3. Consider the rolling resistance: Unlike the golf ball, which can travel through the air with minimal resistance, the bowling ball would experience rolling resistance due to its contact with the ground. The scientist would need to account for this additional resistance when applying the force to the bowling ball.
In summary, the scientist would need to apply more force, for a longer duration, and account for rolling resistance to move the bowling ball to reach 15 mph, compared to the golf ball.
To help the scientist understand what needs to be done differently for the bowling ball compared to the golf ball, we need to consider a few factors. One important factor is the mass or weight of the objects.
The first thing the scientist needs to know is the concept of inertia. Inertia is an object's resistance to changes in its motion. The greater an object's mass, the greater its inertia. In practical terms, this means that objects with more mass will require more force to accelerate or decelerate compared to objects with less mass.
In this scenario, the golf ball and the bowling ball will have different masses. A golf ball typically weighs around 45 grams, while a bowling ball weighs around 6.8 kilograms, which is approximately 150 times heavier than the golf ball.
Assuming the scientist wants both the golf ball and the bowling ball to reach 15 mph (miles per hour), they would have to apply different amounts of force to each ball because of their different masses.
In order for the golf ball to reach 15 mph, the scientist should apply an appropriate force using a golf club or any similar method. Since the golf ball has a smaller mass, it will require less force to achieve the desired speed compared to the bowling ball.
On the other hand, to make the heavier bowling ball reach the same speed of 15 mph, the scientist would need to apply significantly more force compared to the golf ball. This could be achieved by using a stronger push or an inclined surface, such as a ramp or a pulley system, to overcome the bowling ball's higher inertia.
In summary, due to the difference in mass between the golf ball and the bowling ball, the scientist needs to exert more force on the bowling ball compared to the golf ball to achieve the same speed of 15 mph.
In order for both the golf ball and the bowling ball to reach a speed of 15 mph, the scientist would need to consider their different masses and the forces acting on them.
1. Golf ball:
- The golf ball is much lighter than the bowling ball, so it will require less force to reach the target speed.
- To move the golf ball, the scientist could apply a small amount of force, either by hitting it with a club or rolling it with their hand.
- The scientist will need to consider the coefficient of friction between the golf ball and the surface it is on, as well as air resistance, which may be negligible at these speeds.
- With the appropriate amount of force and minimizing friction, the golf ball can reach 15 mph.
2. Bowling ball:
- The bowling ball is much heavier than the golf ball, so it will require a greater amount of force to reach the same target speed.
- The scientist will need to exert more force to accelerate the heavier bowling ball to 15 mph.
- Rolling the bowling ball with their hand may not be enough to reach the desired speed; the scientist might need to use a bowling lane or a ramp to generate more initial force.
- It is important for the scientist to take into account the coefficient of friction between the bowling ball and the surface to minimize the effect of friction.
- Similarly, air resistance should be considered, although it may still be relatively small at this speed.
- By exerting enough force and minimizing friction, the bowling ball can reach 15 mph.
Overall, the main difference is the amount of force required to move each ball due to their different masses. The scientist must consider the appropriate level of force, friction, and other factors to achieve their desired goal of 15 mph for both the golf ball and the bowling ball.
