Question
9) A car goes around a curve traveling at constant speed.
Is there a non-zero net force acting on the car in this case?
Question 9 options:
Yes, a non-zero net force is required for the car to maintain a constant speed with no acceleration as it goes around the curve.
Yes, a non-zero net force is required to produce an acceleration.
No, the car is not accelerating so the net force is equal to zero.

Is the mass of an object the same thing as its weight?
Question 10 options:
No, mass is an intrinsic property of matter, while weight is a force resulting from an object under the influence of Earth's gravitational field.
Yes, used interchangably, mass and weight both indicate the amount of force resulting from an object under the influence of Earth's gravitational field.
Yes, both mass and weight indicate the intrinsic property of matter demonstrated by an object's inertia.

The gravitational force acting on a lead ball is much larger than that acting on a wooden ball of the same size. When both are dropped, does the lead ball accelerate at the same rate as the wooden ball?
Question 11 options:
Yes, they both accelerate at the same rate but the forces are different because their masses are different.
Yes, they will accelerate at the same rate but only if the effect of air resistance is negligible on the lead ball.
No, they accelerate at the different rates because of their difference in size.
Yes, a non-zero net force is required for the car to maintain a constant speed with no acceleration as it goes around the curve.
Yes, a non-zero net force is required to produce an acceleration.
No, the car is not accelerating so the net force is equal to zero.
