Final Review - Forces

Front

What is the formula to calculate mass when net force and acceleration are known?

Back

Mass (m) = Net Force (F) / Acceleration (a)

Front

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

Back

Newton (N)

Front

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

Back

The net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = m * a).

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate or change its motion.

Front

What is the weight of an object?

Back

Weight is the force exerted by gravity on an object, calculated as Weight (W) = mass (m) * gravitational acceleration (g).

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 unbalanced force.

Front

What is tension in a rope?

Back

Tension is the force transmitted through a rope or string when it is pulled tight by forces acting from opposite ends.

Front

How do you calculate the weight of a 100 kg object on Earth?

Back

Weight = mass (100 kg) * gravitational acceleration (9.8 m/s²) = 980 N.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces result in acceleration.

Front

What does it mean for forces to be in equilibrium?

Back

Forces are in equilibrium when the net force acting on an object is zero, resulting in no acceleration.
