Newton's 1st law of motion:
An object that is at rest will stay at rest until a force is applied to the object that makes it move into motion.
Example: A Gymnast that does the bars starts off at rest than force is applied as the gymnast swings and pushes their body over the bar and the force helps them to get into motion.
Newton's 2nd law of motion:
An object's acceleration is dependent on the net force and the mass of an object
Example: On the vault the acceleration of the gymnast is based on how much she/ he weighs. For instance a gymnast that is 90 lbs may not be very strong but will be faster than a gymnast that weighs 130 lbs that is very strong.
