Net force, Periodic Table, Density Review

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

How do you calculate density?

Back

Density is calculated by dividing the mass of an object by its volume (Density = Mass/Volume).

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

What is the unit of measurement for force?

Back

The unit of measurement for force is Newtons (N).

Front

What are examples of forces?

Back

Examples of forces include gravity, friction, tension, and applied force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

If 8 N is applied to the left and 4 N to the right, what is the net force?

Back

The net force is 4 N to the left.

Front

If 15 N is applied to the right and another 15 N to the right, what is the net force?

Back

The net force is 30 N to the right.

Front

What does it mean if forces are balanced?

Back

Forces are balanced when the net force is zero, meaning there is no change in motion.
