Newton's Laws PS2.4 Ps2.5

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 formula to calculate force?

Back

F = ma (Force equals mass times acceleration)

Front

What is the unit of force?

Back

The unit of force is Newtons (N).

Front

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is inertia?

Back

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

Front

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

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 an unbalanced force?

Back

An unbalanced force is a force that results in a change in the motion of an object.

Front

What is the significance of the net force?

Back

The net force is the overall force acting on an object after all the forces are combined.

Front

What is the formula to calculate acceleration?

Back

a = F/m (Acceleration equals force divided by mass)

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.
