Newtons Laws Review

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 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 (F=ma).

Back

Add the magnitudes of the two forces.

What is the definition of mass in physics?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F=ma, where F is force, m is mass, and a is acceleration.

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the larger force.

What is the effect of balanced forces on an object?

Back

Balanced forces do not cause a change in the motion of an object; it remains at rest or continues to move at a constant velocity.

Front

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

Back

The unit of force is the Newton (N).

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

Back

As mass increases, acceleration decreases if the force remains constant (F=ma).
