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?
The crash affects the motion due to the change in velocity, and the crash with the greater force caused a greater change in motion.
The crash affects the motion due to the change in mass, and the crash with the greater mass caused a greater change in motion.
The crash affects the motion due to the change in temperature, and the crash with the higher temperature caused a greater change in motion.
The crash affects the motion due to the change in color, and the crash with the brighter color caused a greater change in motion.

Balanced Forces.
Unbalanced Forces.
Gravitational Forces.
Frictional Forces.

Which toy boat(s) experienced the strongest force when it was bumped? How do you know?
The blue toy boat experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up.
The gray toy boat experienced the strongest force because it had the fastest ending speed.
The orange and gray toy boats experienced the strongest forces because they both gained the same force as they sped up. The blue boat lost force, so it slowed down.
All three toy boats experienced the same strength force because they changed speed by the same amount.
When a car is accelerating, we are used to the idea that the car is going faster. However, in science, when an object (like a car) is accelerating, we are referring to an object:
is going faster
is changing its velocity
is experiencing a net force
All of the Above
In which crash did the skateboard exert a stronger force?
Crash 1
Crash 2
Both crashes exerted the same force
Cannot be determined
In the Olympic sport of curling, a large stone is slid across ice. Even though the stone is on ice, it eventually slows down. Why does the stone slow down?
Because of air resistance
Due to friction between the stone and the ice
Because the stone loses energy
Due to the weight of the stone

Which golf ball(s) experienced the strongest force when bumped? How do you know?
The white and purple golf balls because they gained force, while the green golf ball lost force.
The green golf ball because it takes a stronger force to slow something down than to speed something up.
The green golf ball because it changed speed the most.
The white golf ball because it has the fastest ending speed.
Which soccer ball(s) experienced the strongest force? How do you know?
All three soccer balls experienced the same force because they changed speed by the same amount.
The orange soccer ball; it has more mass and the fastest ending speed.
The blue soccer ball takes a stronger force to slow down a more massive object than to speed it up.
The blue and orange soccer balls; they have more mass than the black soccer ball, but changed speed by the same amount.
