Newton's First Law

Front

What is Newton's First Law of Motion?

Back

Newton's First Law of Motion states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

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

How does mass affect inertia?

Back

Objects with greater mass have greater inertia, meaning they are harder to accelerate or decelerate compared to objects with less mass.

Front

What is meant by an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate. It occurs when the forces acting on an object are not equal and opposite.

Front

What happens to a moving object if no unbalanced force acts on it?

Back

If no unbalanced force acts on a moving object, it will continue to move at a constant velocity in a straight line.

Front

What is the relationship between force and motion according to Newton's First Law?

Back

According to Newton's First Law, the motion of an object is directly influenced by the net force acting on it. If the net force is zero, the object's motion remains unchanged.

Front

Can you give an example of inertia in everyday life?

Back

An example of inertia is when a car suddenly stops, and passengers lurch forward due to their bodies' tendency to continue moving in the same direction.

Front

What is the significance of the term 'net force'?

Back

The net force is the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's Second Law.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in a net force of zero, which means the object's motion does not change.

Front

How does Newton's First Law apply to objects at rest?

Back

Newton's First Law states that an object at rest will remain at rest unless acted upon by an unbalanced force, meaning it will not start moving on its own.
