Newton Laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object; the greater the mass, the greater the inertia.

Front

Which object has the greatest inertia: a rubber ball, a lead ball, a foam ball, or a wooden ball of the same size?

Back

The lead ball has the greatest inertia because it has the greatest mass.

Front

What is the net force when 8 N is applied to the left and 4 N is applied to the right?

Back

The net force is 4 N to the left.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when the net force acting on an object is zero, meaning the object will not accelerate.

Front

What is an example of balanced forces?

Back

An example of balanced forces is when two people push on opposite sides of a box with equal force, resulting in no movement.

Front

What is the net force if an object experiences a force of 4000 N to the left?

Back

The net force is 4000 N to the left.

Front

According to Newton's 1st Law, what happens to an object in motion unless acted upon by an external force?

Back

An object in motion will remain in motion at a constant velocity unless acted upon by an external force.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is an example of Newton's 1st Law in everyday life?

Back

An example is when a car suddenly stops, and passengers lurch forward due to their inertia.

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.
