Net force, Periodic Table, Density Review

Front

What is the sum of all forces acting on an object?

Back

Net force is the sum of all forces acting on an object and is capable of accelerating a mass.

Front

If you push a ping pong ball and a basketball with the same amount of force, which one will go a greater distance?

Back

The ping pong ball will go a greater distance.

Front

How many protons are in the element with atomic number 79?

Back

There are 79 protons in this element.

Front

What information do you need to calculate the density of an object?

Back

You need the mass and volume of the object.

Front

What does it mean if forces are balanced?

Back

If forces are balanced, the net force is zero, and the object does not accelerate.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

How do you calculate the net force acting on an object?

Back

Net force is calculated by adding all the forces acting on the object, taking direction into account.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

What happens to an object's motion if the net force acting on it is not zero?

Back

If the net force is not zero, the object will accelerate in the direction of the net force.

Front

What is the significance of the atomic number in the periodic table?

Back

The atomic number represents the number of protons in an atom and determines the element's identity.
