According to Newton's first law of motion, what happens to an object at rest if no external force is applied to it?
It starts moving at a constant speed
It changes color
It remains at rest
It disappears
According to Newton's second law of motion, what happens to the acceleration of an object if the force acting on it is doubled?
The acceleration of the object will double.
The acceleration of the object will be tripled.
The acceleration of the object will stay the same.
The acceleration of the object will be halved.
