Accelerated Motion - Physics M3

Acceleration is a vector quantity.

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.

The area under a velocity-time graph is the displacement of the object.

The acceleration of an object is the slope of its velocity-time graph.

The sign associated with g, the acceleration due to gravity, depends upon the choice of the coordinate system.

Acceleration is the rate at which an object’s speed changes.

It is not possible to derive an equation of motion for uniform acceleration without a time variable.

Acceleration can never be negative.

The displacement of an object can be calculated by multiplying its velocity and the time interval.

An object that has negative acceleration is definitely doing what?
