Newton's first law states: An _______ at rest stays at _______ an object in motion stays in _______ until acted upon by an _______.

Inertia is the _______ of an object to _______ a change in motion.

If something has a greater mass, then it has more inertia and it requires a greater force to move the object.

Balanced forces - all forces acting on the object are opposite and equal in magnitude.

Unbalanced forces - a change in motion.

Net force is _______.

A force is a _______ or a _______.

Friction is a _______ that opposes motion between two surfaces that are in contact with each other. Friction acts parallel to the surface of contact and in the opposite direction. Types of friction include: _______, _______, _______, _______ or _______.

Give me definitions of: Normal force

Newton's first Law says that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force. Can you think of a real-life example where you have noticed this happening?
