Question

when the force was reduced, the acceleration decreased for both objects. this is called a directly proportional relationship in that as one variable (force) is changed, the resulting variable will change in proportion to the first variable. essentially, if the mass of an object is kept constant and the force is decreased, the resulting acceleration will also decrease. newtons second law is very useful in describing the relationship of force, mass, and acceleration of objects. we use this concept regularly in our daily lives. for example, in cars, newtons second law helps explain why certain cars have a higher or lower gas mileage based on the mass of the vehicle. the greater the mass, the greater the force needed to accelerate it. therefore, larger vehicles generally require more gasoline to travel at the same acceleration as smaller vehicles. the more gas needed for the same acceleration results in a lower gas mileage. who would have thought you could use sir isaac newtons law when buying a car! respond to the question in the box below: 7. summarize newtons second law in your own words. respond to the question in the box below: 8. how did we observe newtons second law in explores 1 & 2 (with the toy jeep / truck) in this class? describe two to three connections.

Explanation:

Newton's second law states that when the mass of an object is constant, force and acceleration are directly proportional. A greater force causes greater acceleration, and a greater - mass object requires more force for the same acceleration. For the second part, since no details about explores 1 & 2 are given, we can assume connections like when more force was applied to the toy jeep/truck, it accelerated more; or when additional mass was added, more force was needed to achieve the same acceleration.

Answer:

1. When mass is constant, force and acceleration are directly proportional. A larger - mass object needs more force for the same acceleration.
2. Possible connections: more force leads to more acceleration; adding mass requires more force for the same acceleration; less force results in less acceleration.
