new to physics. Can you help me to answer these questions? Im a late enrolee, trying to catch up. Thanks!

Which of the following is incorrect regarding Newton's First Law of Motion? 1 pu O An object will remain at rest or will remain in motion if it is already in motion, unless a net external force is acted on it. O When a body is in equilibrium, it must be acted on by no forces, or by several forces such that their vector sum is zero. ()Once a body is set in motion, no net force is needed to keep it moving () The faster the object, the stronger it's Inertia. Which is not considered as a contact force? 1 pu Tension OGravity O Friction Normal Force When a constant force is applied to a body, it moves with uniform: 1 pu Speed ()Velocity O Acceleration Momentum Changes in motion are caused by. 1 pu () unbalanced forces O balanced forces mass O inertia If the force of gravity suddenly disappears: 1 pu () The mass of all bodies will become zero. O The weight of all bodies will become zero O Both will become zero. O Neither will become zero
