Choose an option from the drop-down menu to complete the sentence below. A group of students were researching how the height of ramps affected the distance a toy car traveled. The students tested a toy car on a ramp that was 4 inches high and 4 inches long. The students noticed that the car traveled 3 feet in 4 seconds. The students predicted that if they [CHOICE 1] of the ramp, the same toy car would travel farther.
decreased the height
increased the height
widened the base
narrowed the base
Read the sentences below. Hank was driving his pickup truck down a dirt road. His dog was riding in the bed of the truck. All of a sudden, a opossum ran out in front of the truck. Hank slammed on the brakes to avoid hitting the opossum. This created an unbalanced force acting on the dog in the bed of the truck. How would the force affect the dog?
The dog would slide to the right side of the truck bed.
The dog would slide to the left side of the truck bed.
The dog would slide to the front of the truck bed.
The dog would slide to the back of the truck bed.
Examine the image below. (2 points) As the car in the image above was traveling down the road, the driver took her foot off the gas pedal. Which statements BEST describe the motion of the car after the driver took her foot off the gas pedal?
The car immediately stopped due to Earth's gravitational pull.
The friction between the road and tires gradually slowed the car.
The friction between the road and tires stopped the car immediately.
The car continued to move at the same speed since no other forces were acting on it.
The car gradually slowed due to Earth's gravitational force.
Which of the following are examples of kinetic energy? (2 points)
a runner accelerating to cross a finish line
marbles sitting at the top of a ramp
a batter standing in position to bat a ball
bowling pins sitting at the end of the lane
a bowling ball striking pins at the end of the lane
Students investigate force. The masses they used begin at rest on the ramp. The setup he students use is shown. Which change will reduce the amount of force needed to move the masses?
A. Decrease the height of the ramp
B. Increase the height of the ramp
C. Add an additional mass
D. Pull the spring scale with two hands
A student conducts the investigation shown in the picture. In this experiment a paper cup hangs from a string tied to a single uncooked spaghetti noodle. The student then adds pennies to the paper cup one at a time. Which question is the student most likely trying to answer?
A. how many noodles will it take to hold up the mass of a penny
B. how much force will it take to break the noodle?
C. how long should the string that holds the paper cup be in order to support the greatest amount of pennies?
D. how does the distance between the 2 charis affect the amount of force it takes to break teh noodle?
Students drop the same heavy ball onto identical blockes of soft clay from different heights. For each height they measure the depth of the dent the ball makes in teh clay. Why is the depth of the dent different in each trial?
A. the ball size changes
B. the material of the bll changes
C. the mass of the ball when it hits the clay changes
D. the force of the ball when it hits the clay changes
A student designs an experiment to test the effet of the width of a piece of elastic on the elastic's ability to stretch. The student selects 4 pieces of elastic with different widths but the same length. The student then attaches blocks with different masses to the pieces of elastic. The results of the experiment are shown in teh picture. What should the student do to improve this experiment?
A. use blocks of equal mass on the 4 pieces of elastic
B. use blocks with enough mass to cause the 4 pieces of elastic to break
C. use more than 4 pieces of elastic and 4 blocks
D. use 4 pieces of elastic with different lengths but the same width
