True and False
True
Force and acceleration are related in a linear fashion
True
The net force on an object is the resultant of the force vectors
True
A collision between two moving objects can be represented on a position-time graph
True
A free-body diagram represents forces acting on a system
False
Acceleration can never be negative
True
Acceleration is a vector quantity
False
Acceleration is the rate at which an object's speed changes
False
As the speed of an object moving through a fluid increases, the magnitude of the drag force decreases
False
Force is a scalar quantity
False
It is not possible to derive an equation of motion for uniform acceleration without a time variable
False
Scalar measurements have both magnitude and direction
False
Static friction is exerted on one surface by another when the two surfaces are moving relative to each other
True
Static friction is exerted on one surface by another when there is no motion between the surfaces
True
The acceleration of an object is the slope of its velocity-time graph
True
The area under a velocity-time graph is the displacement of the object
True
The displacement of an object can be calculated by multiplying its velocity and the time interval
False
The equilibrant is equal in magnitude and direction to the net force on an object
False
The position-time graph of an object moving with a constant velocity is never a straight line
True
The process of breaking a vector into its components is called vector resolution
True
The sign associated with g, the acceleration due to gravity, depends upon the choice of the coordinate system.
False
The slope of a position-time graph of an object gives the speed of the object
True
The velocity-time graph of an object in motion with both positive acceleration and zero initial velocity would be a line beginning at the origin and having positive slope
False
The y-intercept of a position-time graph of an object gives the average velocity of the object
True
Vector measurements have both magnitude and direction
True
Vectors can be summed by separately adding the x- and y-components
