Understanding Mass and Inertia

What is the relationship between mass and inertia?

• Mass and inertia are unrelated.

• Greater mass results in a weaker effect of inertia.

• Greater mass results in a stronger effect of inertia.

• Inertia is only affected by the shape of an object.

Why is a bucket filled with sand more difficult to move than an empty bucket?

• Because it is made of a different material.

• Because it is heavier due to gravity.

• Because it has a greater mass, increasing inertia.

• Because it is larger in size.

What property of an object resists changes in its state of motion?

• Weight

• Volume

• Inertia

• Density

How does loading a trolley with groceries affect its movement?

• It moves faster.

• It becomes lighter.

• It becomes more difficult to move due to increased inertia.

• It becomes easier to move.

Why is a car loaded with more items harder to control?

• Because it has less friction.

• Because it has more inertia due to increased mass.

• Because it is more aerodynamic.

• Because it has a lower center of gravity.
