Newton's Laws

Front

What is the net force acting on an object?

Back

The net force is the vector sum of all the forces acting on an object, determining its motion.

Front

Define inertia in the context of motion.

Back

Inertia is the tendency of an object to resist changes in its state of motion, whether at rest or in motion.

Front

What is an unbalanced force and how does it affect motion?

Back

An unbalanced force is a force that causes a change in the motion of an object, resulting in acceleration.

Front

What are balanced forces?

Back

Balanced forces are two equal forces acting in opposite directions on an object, resulting in no change in motion.

Front

Explain the action force in the context of Newton's third law.

Back

The action force is the initial force applied to an object, which results in a reaction force in the opposite direction.

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 a net external force.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more than an object with less mass.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is the significance of the action-reaction pair in Newton's third law?

Back

For every action, there is an equal and opposite reaction, meaning forces always occur in pairs.

Front

How can you identify if forces are balanced or unbalanced?

Back

If the net force is zero, the forces are balanced; if the net force is not zero, the forces are unbalanced.
