Newtons Laws

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 a net external force.

Front

What is Newton's Second 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. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

What unit is used to measure force?

Back

Newtons (N)

Front

If a 10 kg object is accelerating at 5 m/s², what is the force acting on it?

Back

50 Newtons (F = ma = 10 kg * 5 m/s²)

Front

What happens to the acceleration of an object if the mass increases but the force remains constant?

Back

The acceleration decreases.

Front

What is the relationship between mass and force required to accelerate an object?

Back

The more mass an object has, the more force it takes to accelerate it.

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the net force acting on an object is zero, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a net force that causes an object to accelerate.

Front

What is inertia?

Back

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