Newton Laws of Motion

Front

What is Newton's First Law?

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 happens to the force of an object as its acceleration increases?

Back

The force increases.

Front

What is the amount of matter in an object called?

Back

Mass.

Front

If there is a force of 8 N to the left and 4 N to the right, what is the net force? Is this balanced?

Back

Net force is 4 N to the left. No, it is not balanced.

Front

According to Newton's 3rd Law, reactions always go in the ___ direction of the action.

Back

Opposite.

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

Define inertia in the context of Newton's First Law.

Back

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

Front

What is the formula for calculating force?

Back

F = ma (Force equals mass times acceleration).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.
