# Forces (8.6A)

### Determine how UB forces change speed or direction of an object's motion

What is speeding up, slowing down, or changing direction? Acceleration
How do you calculate net force if two forces are going in the SAME direction? Add the forces
How can an object that is not in motion be described? At rest
What kind of forces are acting when an object is at rest or it's moving in a straight line at a constant speed? Balanced forces
What is speed with direction? Velocity
What is distance traveled in a certain amount of time? Speed
What is the total of all forces acting upon an object? Net force
How do you calculate net force if two forces are going in OPPOSITE directions? Subtract the forces
What is the unit in which force is measured? Newton (N)
How do you calculate force? Mass x Acceleration
How do you calculate mass? Force divided by Acceleration
How do you calculate acceleration? Force divided by Mass
What is a push or a pull? Force
What is the unit in which mass is measured? Kilogram (kg)
The amount of matter in an object defines - Mass
What is a force that opposes the motion of one object across another? Friction
What is the unit in which speed is measured? m/s
What is the unit in which acceleration is measured? m/s^2 (meters per second squared)
Which forces cause an object to accelerate? Unbalanced forces
