Describe two differences between mass and weight.

Mass is the amount of matter in an object, and weight is a measure of gravitational force experienced by the object. Mass is constant, while

weight may change with location

Describe how to determine average speed

To determine average speed, divide the total distance by the total time taken to travel that distance.

Discuss how the gravitational forceof Earth affects you.

Include a description of how the gravitational force of the

sun affects you as compared to how it affects Earth.

The gravitational force between me and the Earth is large. The gravitational force of the sun affects me much less than it affects the Earth. The gravity between the sun and planets is large because the

objects have large masses.

To calculate an object’s acceleration, you need to know

a. distance traveled and total time.b. starting point, endpoint, and the object’s mass.c. starting velocity, final velocity, and time it takes to change velocity.d. average speed and direction traveled.

C. starting velocity, final velocity, and time it takes to change velocity.

Describe both speed and velocity, and state the difference between

the two.

Speed is distance over a period of time, and velocity is speed with direction. The difference between speed and velocity is that speed

does not have direction, while velocity does have direction.

A student has a weight of 420 N on Earth. Assume that the moon’s

gravitational force is exactly 1/6 the gravitational force on Earth.

What would be the student’s weight in newtons on the moon?

Explain your calculations.

The student’s weight on the moon would be 70 N, which is 1/6 420 N.

Describe how unbalanced forces affect both moving objects and

nonmoving objects.

Unbalanced forces produce change in the motion of objects. In moving objects, unbalanced forces can change the motion. In non-

moving objects, unbalanced forces can start motion.

Kyle achieved the greatest average speed during the interval between 5 minutes and 10 minutes. The distance traveled during this interval (2

km) was greater than the distance covered in any other 5-minute interval.

During which 5-minute interval

did Kyle achieve the greatest

average speed?

Two forces act on an object. One force has a magnitude of 10 N and is directed toward the north. The other has a magnitude of 5 N directed toward the south. The object experiences a net force of

a. 5 N south. c. 50 N north.b. 15 N north. d. 5 N north.

d. 5 N north.

A hiker’s initial speed at the bottom of the hill is 1.8 m/s and 1.5 m/s when the hiker reaches the top.

It took the hiker 180 s to climb the hill. Explain how to calculate the

hiker’s acceleration, including whether it would be positive or negative.

Subtract 1.8 m/s from 1.5 m/s. Divide that by the 180 seconds that it took the hiker to get to the top of the hill. We know the answer will be negative, because the final speed is slower than the initial speed.
