7th Grade Newton's Laws Ps.7.1.

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 unless acted upon by an external force.

Front

What is the formula for calculating speed?

Back

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define inertia in the context of Newton's First Law.

Back

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

Front

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

Back

Newton (N) is the unit of force.

Front

How do you calculate acceleration?

Back

Front

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

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the force is constant.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object.

Front

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

Back

It will accelerate in the direction of the net force.
