Newton's Laws Flashcards

What is Newton's second law of motion equation?

If you increase the force on an object, its acceleration increases.

If you increase the mass of an object, its acceleration decreases.

To accelerate a 3 kg skateboard at 9 m/s², a force of 3 newtons is needed.

What does the amount of inertia an object has depend on?

Newton's first law of motion states that an object will not experience a change in motion unless acted upon by an unbalanced force.

To increase acceleration of an object, you reduce its mass or increase the applied force.

What does Newton's third law of motion state about forces?

Resistance to change in motion is called stasis.

Action and reaction forces acting in opposite directions do cancel out because they act on different objects.

If you lean against a wall, the wall pushes back on you with a weaker force.

Newton's second law states that an object's acceleration depends on its ________ and on the net force acting on it.

Acceleration is measured in _______.

Force is measured in a unit called the _________.

The smaller the mass of an object, the ______ its inertia.

Newton's Laws of Motion

Newton's second law: ( F = MA ), which describes the relationship between force (F), mass (M), and acceleration (A).
Increasing the force applied to an object results in increased acceleration, demonstrating a direct relationship.
Increasing an object's mass leads to a decrease in acceleration, indicating an inverse relationship.
To accelerate a 3 kg skateboard at 9 m/s², a force greater than 3 newtons is required, disproving the assertion that only 3 newtons is needed.
The inertia of an object is determined by its mass, not its speed; mass quantifies resistance to changes in motion.
Newton's first law states that an unbalanced force is necessary for an object to change its state of motion.
Acceleration can be increased by either reducing the mass of an object or increasing the net applied force.
Newton's third law asserts that when one object exerts a force on another, the second object exerts an equal and opposite force.
"Inertia" refers to the resistance to change in motion, contradicting the term "stasis."
Action and reaction forces act in opposite directions but do not cancel each other out as they act on different objects.
When leaning against a wall, the wall exerts an equal force back, refuting the idea that it exerts a weaker force.
An object's acceleration is influenced by its mass and the net force acting on it.
Acceleration units are expressed in meters per second squared (m/s²).
Force is quantified in newtons (N), which is the standard unit of measurement.
A smaller mass results in smaller inertia, highlighting the dependence of inertia on mass.
