Mod. 2 Review Newton's Laws of Motion

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the definition of net force?

Back

The vector sum of all the forces acting on an object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change the motion of an object, while unbalanced forces cause a change in motion.

Front

What is the standard unit of force?

Back

Newtons (N).

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the definition of velocity?

Back

Velocity is speed in a given direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is gravitational force?

Back

The attractive force between two masses.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point.
