An outside force acts on it, it applies a force to something, or it converts mass into energy.
Not sure about the last one.
Three ways something can accelerate are 1. increase speed 2. change direction 3. both.
Gravity causes falling objects to accelerate.
objects can be moved by human or by machines
no, most objects accelerate differently.
Radiation and conduction

All objects accelerate if the forces acting on them are not balanced.
Objects will accelerate if there is a net force acting on them.
Gravity causes falling objects to accelerate.
cars and buses
objects can be moved by human or by machines
The three ways are: radiation, conduction, and convection.
no, most objects accelerate differently.
Radiation and conduction
When the forces on an object are unbalanced, the object will accelerate in the direction of the net force.
because they are fat
balance
