Laws of Motion

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, acting in the opposite direction to the object's movement.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration or a change in direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning it will remain at rest or continue moving at a constant velocity unless acted upon by an external force.

Front

What is the relationship between action and reaction forces?

Back

According to Newton's Third Law, for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object, determining the object's acceleration.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that 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 friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact, acting parallel to the surfaces.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the effect of mass on acceleration?

Back

The greater the mass of an object, the less acceleration it will experience for a given force, according to Newton's Second Law.
