The British scientist that published a st of 3 rules in 1687 that explained how forces and motion are related.
Who is Isaac Newton ?
100
Acceleration of an object is in the same direction as the net force on the object.
What is Newton's Second Law of Motion?
100
Fnet=ma
What is the formula to solve net force?
200
If the net force acting on an object is zero, the object remains at rest, or if the object is moving, it continues moving in a straight line with constant speed.
What is Newton's First Law of Motion?
200
If you observe a change in an objects velocity.
How do you know an unbalanced force has acted on an object?
200
Fnet/m (Fnet over m)
What is the formula to Newton's Second Law of Motion?
300
Only changes when there are unbalanced forces acting on it.
What is velocity?
300
T/F Acceleration is the change in velocity divided by the time needed for the change to occur.
What is true?
300
As a result of these, a person in a car crash slows down at the same rate as the car slows down, keeping them from being thrown out of the car or moving after the car stops.
What are safety belts?
400
The tendency of an object to resist a changr in its motion.
What is inertia?
400
The accleration of an object depends on its mass, as well as the net force exerted on it.
What is the relationship of mass and acceleration?
400
T/F In a car crash, inertia causes an unrstrained passenger to continue moving at the speed of the car before the crash occured.
What is true?
500
What inertia depends on.
What is an objects mass in relation to inertia?
500
T/F Net force, mass and acceleration are completely unrelated except for in Newton's Second Law?
What is false?
500
The acceleration of an object depends on the mass of the object and the ________ exerted on the object.
