What term means a push or pull on an object?
What is a FORCE?
What must happen for an object to change its velocity?
What is A FORCE MUST BE EXERTED?
What equation tells us how to calculate speed?
What is SPEED = DISTANCE ÷ TIME?
How is force applied when two objects collide?
What is A FORCE IS EXERTED ON EACH OBJECT?
What two things describe velocity?
What is SPEED & DIRECTION?
What word means to apply a force to something?
What is EXERT?
A force exerted in the same direction as an object's motion causes what change?
What is SPEED UP?
If the same force is applied to two objects of different masses, which one will move faster?
What is THE ONE WITH LESS MASS?
What can you infer if Object X barely changes direction in a collision with Object Y?
What is OBJECT X HAS MORE MASS THAN OBJECT Y?
A weaker force is applied to an object with a mass of 5kg. The same weaker force is applied to an object with a mass of 15kg. With which object would the weaker force cause a greater change in velocity?
What is THE OBJECT WITH LESS MASS THAN THE OTHER OBJECT?
What do we call a result that happens because of an event?
What is an EFFECT?
A force exerted in the opposite direction of an object's motion can cause what three changes?
What is SLOW DOWN, STOP, OR GO IN THE OPPOSITE DIRECTION?
Why are racing wheelchairs lighter than rugby wheelchairs?
What is TO INCREASE SPEED?
What is TO HAVE A GREATER CHANGE IN VELOCITY?
In Claim 2, the thrusters fire on the space pod, slow it down, then the space pod bumps into the space station. What happens to the pod’s motion after it collides with the space station?
What is IT CHANGES VELOCITY (speed and direction)?
It slows down and goes in the opposite direction.
If no force acts on an object, what happens to its motion?
What is ITS VELOCITY STAYS THE SAME?
This term means the speed in a certain direction.
What is VELOCITY?
If two pods are pushed with different force strengths, which force will cause a greater change in velocity?
What is THE STRONGER FORCE?
What happens to the change in velocity of an object when mass increases but force strength stays the same?
What is THE CHANGE IN VELOCITY DECREASES?
TRUE OR FALSE
Only one object feels a force in a collision.
What is FALSE?
Both objects feel equal and opposite forces.
Why do we see slower changes in motion for Object X (25kg) than Object Z (13kg)?
What is OBJECT X HAS MORE MASS?
What is the term for the force between an object and the surface it is moving over?
What is FRICTION?
What kind of reasoning helps explain why a motion changed the way it did?
What is CAUSE AND EFFECT?
In Claim 2 of our studies, the space pod only slowed down when the thrusters were fired then bumped into the space station. The thrusters on the ACM pod were just as strong as normal missions — so what was different about the pod in this mission?
What is IT WAS MORE MASSIVE?
True or False
A collision only occurs when two objects are moving towards each other and hit each other.
What is FALSE?
A collision can also occur when an object bumps into an object that is not moving. It can also occur when an object is going one direction, and another object bumps into it from behind, causing it to speed up.
What is the relationship between force strength, mass, and change in velocity?
What is A STRONGER FORCE CAUSES A GREATER CHANGE IN VELOCITY?
What is A WEAKER FORCE CAUSES A SMALLER CHANGE IN VELOCITY?
What is SMALLER MASS CAUSES A GREATER CHANGE IN VELOCITY?
What is GREATER MASS CAUSES A SMALLER CHANGE IN VELOCITY?
