Newton Laws of Motion

Front

What is Newton's First 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

What is the definition of force?

Back

A push or pull that causes a change in the motion of an object.

Front

What are unbalanced forces?

Back

Forces that cause a change in the motion of an object because they are not equal in size and opposite in direction.

Front

What is the relationship between force, mass, and acceleration according to Newton's Second Law?

Back

Force equals mass times acceleration (F = ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What happens to an object's motion when the net forces acting on it are zero?

Back

The object remains in constant motion in a straight line or stays at rest.

Front

How does increasing the mass of an object affect its acceleration when a constant force is applied?

Back

Increasing the mass decreases the acceleration.

Front

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

Back

Newton (N).

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How do balanced forces affect an object's motion?

Back

Balanced forces do not change the motion of an object; it remains at rest or in constant motion.
