Newton's Laws of Motion

Front

Objects in motion tend to stay in motion, while objects at rest, tend to _____________.

Back

stay at rest (This is a statement of Newton's First Law of Motion, also known as the Law of Inertia.)

Front

_______ force is needed to move objects of larger mass.

Back

More (According to Newton's Second Law of Motion, more force is required to accelerate objects with greater mass.)

Front

An object's motion won't change unless acted on by a _________.

Back

force (This principle is part of Newton's First Law of Motion.)

Front

This force is caused by air and slows things down.

Back

Air Resistance (Air resistance is a type of friction that acts against the motion of objects moving through the air.)

Front

______________ forces do not affect the movement of an object.

Back

Balanced (Balanced forces are equal in size and opposite in direction, resulting in no change in motion.)

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
