Accelerated Motion - Physics M3

Acceleration is a vector quantity.

• True

• False

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

• True

• False

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

• true

• false

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

• true

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

• true

• false

Acceleration can never be negative.

• true

• false

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

• true

• false

An object that has negative acceleration is definitely doing what?

• speeding up

• accelerating in a direction that is opposite to a stated positive direction

• slowing down

• maintaining a constant speed
