SI unit of length
The ________ or distance is the meter (m)
Acceleration
________ occurs when an object changes its speed, its direction, or both.
Inertia
________: the tendency of an object to resist any change in its motion.
Velocity
________: includes the speed of an object and the direction of its motion.
Displacement
________: the distance and direction of an objects change in position from the starting point.
Reference Point
A(n) ________ is needed to determine the position of an object.
Slope
The ________ of a line on a distance- time graph equals the speed.
Net Force
________: When two or more forces act on an object at the same time.
Motion
________ occurs when an object changes its position relative to a reference point.
Uniform Motion
If an object is moving, it will have ________.
Horizontal Line
A(n) ________ on a distance- time graph has zero slope, and represents an object at rest.
Acceleration
________ also has direction, just as velocity does.
Acceleration
________: the rate of change of velocity.
Distance
how far an object has moved
Speed
the distance an object travels per unit of time
Average Speed
the total distance traveled divided by the total time of travel
Instantaneous Speed
the speed at a given point in time
Velocity
includes the speed of an object and the direction of its motion
Force
a push or pull
Net Force
When two or more forces act on an object at the same time
Balanced Forces
Forces on an object that are equal in size and opposite in direction
Inertia
the tendency of an object to resist any change in its motion
