Forces and Newtons Laws

Front

What is the definition of a force?

Back

A force is a push or pull acting on an object.

Front

If an object has zero net force, what can be said about its motion?

Back

It can be moving at a constant velocity.

Front

What happens to an object at rest if no outside forces are applied?

Back

It will stay at rest.

Front

Which of Newton's laws states that an object in motion stays in motion unless acted upon by an outside force?

Back

Newton's First Law of Motion.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that do not cancel each other out, resulting in a change in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's Second 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.

Front

How do you calculate force using Newton's Second Law?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.
