Newton's Laws of Motion

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in the motion of an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it rubs against another surface.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the center of the Earth.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, slowing it down.

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 role of mass in motion?

Back

Mass is a measure of the amount of matter in an object, affecting how much force is needed to change its motion.

Front

What happens when unbalanced forces act on an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change shape.
