Force & Motion Flashcard

Front

What is the relationship between mass, acceleration, and force?

Back

The greater the mass or acceleration, the greater the force (Newton's Second Law).

Front

What do we call forces that are not equal and act on the same object from different directions?

Back

Unbalanced Force.

Front

What does Newton's 1st Law state about an object at rest?

Back

An object at rest stays at rest until an unbalanced force acts upon it.

Front

True or False: An object in motion remains in motion with the same speed and direction unless acted upon by a balanced force.

Back

False. It remains in motion unless acted upon by an unbalanced force.

Front

How is acceleration measured?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

What is Newton's 2nd 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.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is inertia?

Back

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

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
