Front

Label the parts of an atom and their charges

Back

Electrons: in orbit around protons and neutrons.

Protons: at the nucleus of the atom in groups of 3.

Neutrons: at the nucleus of the atom in groups of 3.

Nucleus: The protons and Neutrons

Orbit: The orbit electrons go through

Front

Define the word force and list at least 5 different forces at work in the world around you.

Back

Definition: strength or energy as an attribute of physical action or movement.

Different forces may vary.

Front

Describe the difference between contact and non-contact forces. List 3 examples of each.

Back

Contact forces occur due to the direct contact between two different objects. There is no field (area) of force linked with the contact force.

Non-contact forces occur due to either attraction or repulsion between two objects such that there is no direct contact between these objects. A field (area of force) is linked with the non-contact force.

Front

Explain how forces are measured and what SI unit is used to measure a force.

Back

The SI unit for force is Newton (N), named after Sir Isaac Newton.

1 N is defined as the amount of force needed to move 1 kilogram of mass 1 meter/second

Front

Describe the 3 main ways forces can interact with each other.

Back

Forces can interact in 3 main ways: 

They can act in the same direction.

They can act in opposite directions

They can act at angles to one another.

Front

Calculate the net (overall) force on an object when forces are acting on it.

Back

To calculate the net (overall) force on an object(s) in opposite directions, you can assign the force exerted in one direction a positive number (+) and assign the force exerted in another direction a negative number (-).

Front

Use examples to describe the difference between kinetic energy and potential energy.

Back

When you hold a ball up it has potential energy and when you drop it the potential energy becomes kinetic.

On the top of a roller coaster, you have potential energy and when you drop you release all the potential energy and it becomes kinetic energy.

Front

Identify and distinguish between the independent & dependent variables in an experiment.

Back

Independent variables change in the experiment and dependent variables change due to the independent.
