If the net force of an object is not zero it is?
What is an unbalanced force
200
What is the formula for calculating speed?
What is speed equals distance/time
200
On a distance time graph what label is on the horizontal and vertical axes?
What is distance on vertical and time on horizontal
200
The tendency to resist change in motion is?
What is Inertia
200
The combination of all forces act on an object is?
What is a net force

If Jake walks 40m in in 15 seconds what is his speed?
What is 2.66m/s
300
A line on a distance time graph becomes steeper as an object's speed does what?
What is increases
300
What is the measure of difficulty to stop an object?
What is momentum
300
Describe Newtons first law?
What is an oject at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an outside force.
300
Describe Newton's second Law?
What is force equals mass times acceleration. The force needed to change the motion of an object depends on its mass.
