Inertia by definition is the propter of things to resist changes in motion. This quantity is directly related to an object’s mass, or how much of ‘something’ and object is made of. Therefore, could Inertia change if your object were to travel into space? Could it change if your object was on the moon? If not, explain how you could change an object’s inertia.

- Which of the following statements are true of inertia? List all that apply. Inertia is a force. Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects. An object would not have any inertia in a gravity-free environment (if there is such a place). Inertia is the tendency of all objects to resist motion and ultimately stop. In a gravity-free environment (should there be one), a person with a lot of inertia would have the same ability to make a turn as a person with a small amount of inertia.Spring Gun: Planet X was just discovered orbiting a nearby star! It orbits a start that is 6.9 times the mass of our sun in a solar system just 31.3 light-years away. The acceleration due to gravity there is 0.07 g. After making some measurements in lab, you start to daydream about travel to other planets. Your spring gun can launch a projectile with a speed of 3.7 m/s. What would happen if you were to launch a projectile at an angle of 32 ° above horizontal on Planet X? (a) What maximum height would the projectile reach? (b) How far would the projectile travel before it hit the ground? Assume the projectile lands at the same height it was launched from.Which of the following statements are true of inertia? Inertia is a force. An object would not have any inertia in a gravity-free environment Fast-moving objects have more inertia than slow-moving objects. All objects have inertia.
