What are balanced forces?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

State Newton's 1st Law of Motion.

Back

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

What does Newton's 2nd Law of Motion state?

Back

Newton's 2nd 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).

Explain Newton's 3rd Law of Motion.

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What is a net force?

Back

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

How does friction affect motion?

Back

Friction is a force that opposes the motion of an object, affecting its acceleration and velocity.

What is the significance of the term 'action-reaction' in Newton's 3rd Law?

Back

The term 'action-reaction' refers to the paired forces that occur when two objects interact; they are equal in magnitude and opposite in direction.

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.
