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?
What happens when two objects collide?
What is EACH OBJECTS EXERTS A FORCE ON THE OTHER 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, which one will move faster?
What is THE ONE WITH LESS MASS?
The forces during a collision are equal in what two ways?
What is EQUAL IN STRENGTH, OPPOSITE IN DIRECTION?
When can a weaker force still change an object’s velocity?
What is THE OBJECT HAS LESS MASS THAN ANOTHER OBJECT?
What is IT IS EXERTED OVER A LONGER PERIOD OF TIME?
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?
What happens to the pod’s motion after it collides with the space station?
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?
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 massive objects?
What is THEY HAVE 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?
The thrusters on the ACM pod were just as strong as normal missions —so why did it move differently?
What is THE MASS WAS DIFFERENT?
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.
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?
