Question
5)
Two equal forces act on two different objects, one of which has a mass ten times as large as the other. Will the more massive object have a larger acceleration, an equal acceleration, or a smaller acceleration than the less massive object?
Question 5 options:
The larger mass has a larger acceleration since the ratio of the accelerations will be proportional to the ratio of the masses.
The larger mass has a smaller acceleration since the ratio of the accelerations will be the inverse of the ratio of the masses.
The acceleration of the larger mass is equal to the acceleration of the smaller mass since the ratio of the accelerations will be equal to the ratio of the masses.
There is not enough information to determine the relative accelerations.
7)
An object moving horizontally across a table is observed to slow down. Is there a non-zero net force acting on the object?
Question 7 options:
Yes, there must be a net force directed opposite the motion to produce the observed negative acceleration.
No, a non-zero net force cannot exist due to conservation of energy.
No, the force acting on the object must be equal to zero so that it will slow down.
Yes, there must be a net force in the same direction of the motion to produce the observed negative acceleration.
8)
A car goes around a curve traveling at constant speed.
Is the acceleration of the car zero in this process?
Question 8 options:
Yes, but only if the road is banked so that the car can maintain a constant speed around the curve.
Yes, the acceleration is zero because the speed of the car is constant.
No, the velocity of the car is continuously changing direction while on the curve so there is acceleration.
The larger mass has a larger acceleration since the ratio of the accelerations will be proportional to the ratio of the masses.
The larger mass has a smaller acceleration since the ratio of the accelerations will be the inverse of the ratio of the masses.
The acceleration of the larger mass is equal to the acceleration of the smaller mass since the ratio of the accelerations will be equal to the ratio of the masses.
