bellringer In your composition book, write the question and answers 1. Explain newton's first law in your own words 2. Explain inertia in your own words 3. What are some differences between balance and unbalance forces

6. 1 newton's first law davis

The first law of motion (newton's first law) ● States that objects will continue the motion they already have unless they are acted on by a net force ● When the net force is 0, objects at rest stay at rest and objects in motion keep moving with the same speed and direction

Newton's first law cont. The first law says there can be no change in motion without a net force, this includes slowing down

Balances and unbalanced forces ● Changes in motion come from unbalanced forces. ● If forces are truly balanced, a moving object will keep moving forever with the same speed, in the same direction

Inertia ● ● Inertia is a property of an object that resist changes in motion. Inertia comes from MASS Objects with more mass have more inertia The greater an objects inertia, the greater the force needed to change its motion
