Laws of Motion Practice

Front

Forces that are equal in size but in opposite directions are called ______________ forces.

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

What is Newton's First Law of Motion?

Back

Newton's First Law states that 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 the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

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

Back

According to Newton's Second Law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, changing its velocity.
