Newton's Laws of Motion

Front

What is Newton's first 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 an unbalanced force.

Front

What is the law of inertia?

Back

It is another name for Newton's first law of motion, which states that objects resist changes in their state of motion.

What happens to objects in a moving vehicle when it suddenly stops?

Back

Objects inside the vehicle will continue moving forward due to inertia, potentially sliding toward the front.

Front

What is the standard unit of force?

Back

The standard unit of force is the Newton (N).

According to Newton's second law, what is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

If you increase the force applied to an object, what happens to its acceleration?

Back

The acceleration of the object increases.

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

Back

Greater mass results in less acceleration when the same force is applied.

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, reducing its acceleration.

Front

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate.
