Answer 1

$\displaystyle\sf{\bold{\underline{Acceleration}}$

$\displaystyle\sf{Acceleration \:is \:the \:rate \:of \:change \:of \:the \:velocity \:of \:an \:object \:with \:respect \:to \:time.$

$\displaystyle\sf{Accelerations \:are \:vector \:quantities.$

The SI unit for acceleration is metre per second squared (m/s²)

The magnitude of an object's acceleration, as described by Newton's Second Law, is the combined effect of two causes:

• the net balance of all external forces acting onto that object — magnitude is directly proportional to this net resulting force;

• that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass.
