Newtons Laws Review

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does Newton's First Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

F=ma, which means that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Front

What is Newton's Third Law of Motion?

Back

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

Front

How do you calculate net force when two forces are acting in the same direction?

Back

You add the magnitudes of the two forces together.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, and the object will accelerate in the direction of the larger force.

Front

What is an example of Newton's Third Law?

Back

When a rocket launches, the engines push down on the ground, and the ground pushes the rocket upward with an equal and opposite force.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, for a given force, acceleration decreases.
