Newtons Laws

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

Define inertia in the context of Newton's Laws.

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

What are unbalanced forces?

Back

Unbalanced forces are forces that cause a change in the motion of an object; they result in a net force acting on the object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

State Newton's 2nd 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 does Newton's 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

How does mass affect 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 the relationship between force, mass, and acceleration?

Back

According to Newton's 2nd Law, force equals mass times acceleration (F=ma).

Front

Give an example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone applies a force to move it.

Front

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

Back

Net force is the total force acting on an object after all the individual forces are combined; it determines the object's acceleration.
