Force & Motion and Newton's Laws

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as Speed = Distance/Time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does Newton's 1st Law state?

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 does Newton's 2nd Law state?

Back

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

Front

What does Newton's 3rd Law state?

Back

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

Front

What is the difference between balanced and unbalanced forces?

Back

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

Front

What is inertia?

Back

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

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.
