What is a Net Force?
the sum of all forces that are acting on a object.
The total force multiplied together.
The total amount of force that is applied to the object.
How does the mass of an object affect it's motion?
It has no effect
The less the mass the less effect a force will have
The greater the mass the greater the effect a force will have
The greater the mass the less effect a force will have
A runner races in the 100 meter dash. It takes her 10 seconds to finish. What is her average speed?
10 m/s
1000 m/s
100 seconds
10 seconds
Distance formula
S X T
T X S
T/D
D/T
Time formula

1 km/hr
The 2 objects have the same average speed over the 7 seconds. Why?
Both objects traveled the same distance in the same amount of time.
The graph for Object B is steeper at the end of the time.
Object B has sections of zero speed while Object A is never stopped
The final position on the graph for Object A is much greater.
