According to Newton's First Law of Motion, an object at rest will remain at rest unless acted upon by:

• A balanced force

• An unbalanced force

• Gravity

• Friction

Which of the following best describes Newton's Third Law of Motion?

• An object in motion stays in motion

• Force equals mass times acceleration

• For every action, there is an equal and opposite reaction

• The acceleration of an object depends on the net force acting upon it

NGSS.MS-PS2-1

Which of the following best describes Newton's First Law of Motion?

• An object will remain at rest or in uniform motion unless acted upon by an external force.

• The force acting on an object is equal to the mass of the object times its acceleration.

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is directly proportional to the net force acting on it.

Which of the following statements is true about inertia?

• Inertia is the tendency of an object to change its state of motion.

• Inertia is the tendency of an object to resist changes in its state of motion.

• Inertia is the force that causes objects to move.

• Inertia is the acceleration of an object due to gravity.

Design an experiment to test Newton's Third Law of Motion using everyday materials.

• Drop various objects to see if they fall at the same rate

• Push against a wall and measure the force exerted back

• Roll different masses down an incline and measure their acceleration

• Suspend two balloons and blow air between them to observe reactions
