1. Three toy boats with the same mass were in a lake. Two boats were moving and one was stopped. Each boat got bumped by another boat, but not in the same direction. All the boats changed speed as a result of being bumped. Use the information in the diagram to answer. Which toy boat(s) experienced the strongest force when it was bumped? How do you know?
What is "The orange and gray toy boats experienced the strongest forces because they both gained the same force as they sped up.The blue boat force, so it slowed down."
2. Three chairs were rolling across a flat office floor. The blue and red chairs are the same mass, and they have more mass than the yellow chair. Each chair was hit by another chair, but not from the same direction. Use the information in the diagram to answer.
Which chair(s) experienced the strongest force when hit? How do you know?
What is "A. The blue and red chairs experienced the strongest force because they are both more massive than the yellow chair and they changed speed by the same amount.''
5. Miniature golf is a game in which players hit a golf ball with a club, which causes the ball to roll along the flat ground. Three golf balls with the same mass were rolling on the ground. Each ball was hit by a golf club, but not from the same direction. All the golf balls changed speed as a result of being hit. Use the information in the diagram to
answer.Which golf ball(s) experienced the strongest force when hit? How do you know?
What is " 5.C. The green golf ball because it changed speed the most.''
7. Mateo and Jackie were on a playground rolling some different-sized balls to get them to crash. They used a tennis ball (the same mass) in both crashes. They tried two soccer balls—a pink one (more mass) for Crash 1 and a blue one (less mass) for Crash 2. Mateo and Jackie want to know what happened to the tennis ball. Use information from the diagram to answer. In which crash did the tennis ball experience a stronger force? How do you know?
A. Crash 1, the force on the soccer ball was stronger in this crash, so the force on the tennis ball was also stronger.
9.Three friends were kicking soccer balls at a neighborhood field. Three soccer balls were rolling across the field. The black soccer ball has less mass than the blue and orange balls, which have equal mass. All three soccer balls were kicked by one of the friends, but not all from the same direction. Use the information in the diagram to answer.Which soccer ball(s) experienced the strongest force? How do you know?
D. The blue and orange soccer balls; they have more mass than the black soccer ball, but changed speed by the same amount.
3.Scott and James work at a grocery store. After the grocery store closed, they were playing a game with a shopping cart and Scott’s skateboard. They crashed the skateboard and the shopping cart two times. The shopping cart had more mass in Crash 2 than it did in Crash 1. Use the information in the diagram to answer. In which crash did the skateboard experience a stronger force? Why?
What is ''B. Crash 2, the force on the cart was stronger in this crash, so the force on the skateboard was also stronger''
4.Sandra pushed a wooden block and it slid across the floor. The wooden block gradually slowed down and stopped after moving 10 meters. Why did the block stop moving?
What is " A. The floor exerted a force that is opposite to the direction of the block's motion.''
6.Hockey is a sport in which players use hockey sticks to push a puck across smooth ice. At practice one day, three different-colored hockey pucks were sliding on the ice. The green hockey puck has less mass than the black and purple hockey pucks, which have the same mass. A player hit each hockey puck with a stick, but not from the same direction. Use the information in the diagram to answer.Which puck(s) experienced the strongest force when hit? How do you know?
A. All three hockey pucks experienced the same force because they changed speed by the same amount.
8.Officials are looking into three different ski accidents. The accidents happened when three skiers (all with the same mass) were skiing across flat, snowy ground. They were each bumped by another skier, but not all from the same direction. These skiers changed speed as a result of being bumped. Use the information in the diagram to answer.Which skier(s) experienced the strongest force when bumped? How do you know?
D. The skier in the red sweater because it takes stronger force to slow something down than to speed it up.
10. Scientists created models that show a rocky asteroid crashing into a moon (less mass) and a planet (more mass). In both crashes, the asteroid was the same mass. Scientists want to know what happened to the asteroid. Use the information in the diagram to answer. In which crash did the asteroid experience a stronger force? How do you know?
A. Crash 2; the force on the planet was stronger in this crash, so the force on the asteroid was also stronger.
11. At dinner, Hans passed the salt shaker to his sister Jessica by sliding it across the wooden table. The salt shaker gradually slowed down and stopped after moving 12centimeters.Why did the salt shaker stop moving?
B. The table exerts a force that is opposite to the salt shaker's motion.
12. Curling is a sport in which players push large stones across smooth ice. Three curling stones that have the same mass were sliding across the ice. They were each pushed by a player, but not all from the same direction. Each curling stone changed speed as a result of being hit. Use the information in the diagram to answer.Which curling stone(s) experienced the strongest force when hit? How do you know?
C. The orange curling stone experienced the strongest force because it ending speed
13. Kristina has three skateboards for her skateboarding competitions. The brown and pink skateboards are of equal mass and more massive than the green skateboard, which has the least mass. One day, she tested the skateboards by giving each a push, but not from the same direction. Use the information in the diagram to answer. Which skateboard(s) experienced the strongest force from Kristina’s push? How do you know?
B. The brown skateboard experienced the strongest force because it requires more force to slow an object down than to speed it up.
14. After hockey practice, Carissa and Keenan were playing a game where they were pushing some objects to get them to crash. They were using a cone and two different pucks—a black one with more mass for Crash 1 and a blue one with less mass for Crash 2. They want to know what happened to the cone. Use the information from the diagram to answer.In which crash did the cone experience a stronger force? How do you know?
B. The diagram doesn't tell you anything about the force on the cone. It only gives information about the force on the pucks.
