Newtons are measured using this instrument.
What is a spring scale?
Force is measured in ________________ units.
What are Newtons?
The direction and distance from the starting point to the ending point
What is displacement?
The measurement of how long it takes an object to get from one place to another is _____________. What type of unit is used to label this?
What is speed and m/s or cm/s?
Describe how you find the Net Force of an object.
What are you add the forces that are going in the same direction and subtract the forces going in opposite directions?
What is the formula for speed and its units?
Speed = distance/time and m/s or cm/s
The difference between speed and velocity
Speed is how fast something is going and velocity is how fast it is going in a certain direction.
Formula for acceleration and its units
What is Final Velocity minus Initial Velocity divided by Final Time minus Initial Time and m/s2 (squared)?

What are static, kinetic/sliding, rolling and fluid?
On a distance/time graph, a horizonal line represents this
What is resting or stopped?
A horizontal line on a velocity/time graph means this
What is a constant speed?
The formula for average speed
What is Average Speed = Total Distance Covered divided by Total Time Taken?
A upper curved line on a distance/time graph means this
What is acceleration?
A downward diagonal line on a velocity/time graph means this
What is deceleration or negative acceleration?
View the Speed/Time graph and tell the distance the bus traveled during segment AB.
What is 50m?
Review the graph and tell which graph shows deceleration
What is F?
Review the graph. Which graph shows a constant speed?
What is G?
Review the graph. Which graph shows that the walker is coming back?
What is 67?
Review the graphs. Which graph shows both runners moving at the same speed?
What is 41?
Review the graph. Which graph is the walker stopped?
What is 69?

What is A?
A car has a mass of 1200 kilograms. It is traveling on the highway at 65 m/s. What is its momentum?
Formula for momentum is momentum = mass of object x velocity of object
M= 1200 kg x 65m/s
78000 kg x m/s
