A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know about the speed and direction of the satellite after the crashes. Why would the crash affect the motion of the satellite, and which crash caused a greater change in motion for the satellite?
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?
The blue curling stone experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up.The , blue curling stone, experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up.
The blue curling stone experienced the strongest force because it changed speed the most.The , blue curling stone, experienced the strongest force because it changed speed the most.
The orange curling stone experienced the strongest force because it has the fastest ending speed.The , orange curling stone, experienced the strongest force because it has the fastest ending speed.
The yellow and orange curling stones experienced the same strong force because they both gained force, but the blue curling stone lost force.
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?
There was no force on the asteroid. Only the moon and planet experienced a force in each crash.There was , no force, on the asteroid. Only the moon and planet experienced a force in each crash.
The force was the same in both crashes. The planet and moon changed speed by the same amount so that means the force on the asteroid was the same in both crashes.
Crash 2; the force on the planet was stronger in this crash, so the force on the asteroid was also stronger.Crash 2, ; the force on the planet was stronger in this crash, so the force on the asteroid was also stronger.
The diagram doesn’t tell you anything about the force on the asteroid. It only gives information about the force on the planet and the moon.The diagram , doesn’t tell you anything about the force, on the asteroid. It only gives information about the force on the planet and the moon.
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 12 centimeters.
Why did the salt shaker stop moving?
All objects stop moving because their natural state is to be still.
The table exerts a force that is opposite to the salt shaker's motion.
The table absorbs force from the salt shaker.
The salt shaker ran out of force.The salt shaker ran out of force.
A proportional model has been created to analyze the relationship between force, mass and acceleration in the collision. Calculate the force and acceleration of each object below.
Object A has a force of 9N, Object B has a force of 36 N. The acceleration of Object B after the collision is 9 m/s^2
Object A has a force of 36N, Object B has a force of 36N. The acceleration of Object B after the collision is 6m/s^2
Object A has a force of 36 N, Object B has a force of 36 N. The acceleration of Object B after the collision is 216 m/s^2
