It is an interaction which, if unbalanced, will change the shape or change the movement of an object.
force
The closest known galaxy to the milky way is called the Canis Major Dwarf Galaxy. True or false?
true
it means a force or moments are unbalanced if their effects add together or are opposite but do not completely cancel out.
unbalanced
Ceres looks like a small planet round with a diameter of 975 km and is covered with CRATERS. It has a core, mantle & crust like some planets. True or false?
true
constant means the value is not the same for every input value. True or false?
false
This milky band/milky way is not part of the GALAXY where we live in. True or false?
false - it is part of our galaxy
graph is the way of expressing the relationship between two quantities, out of which one alters as an after-effect from the other. True or false?
true
The different colours you see on a mobile phone, computer or television are all produced from combinations of the three primary colours. true or false?
true
And as the particles in a liquid are moving randomly in all directions, then the pressure in the liquid is equal in all directions. True or false?
True
It is the distance from the bottom of something to the top.
depth
When you look at a NON-LUMINOUS object, you see the light that is reflected from the object. true or false?
true
it means the speed is decrease.
slow down
Sea level is the position of the surface of the ocean, usually taken mid-way between high tide and low tide. True or false?
True
It is a rigid length of material that can turn about a pivot.
lever
More force - more pressure. More area - less pressure. True or false?
True
Violet light is refracted through the largest angle and red light is refracted through the smallest angle. true or false?
true
It means to work out a value using a mathematical method or equation.
calculate
It is the path taken by a moving object, or the line along which a force acts.
direction
It means to hit into something.
collide
The Earth’s atmosphere, which we call air, is made from gases. True or false?
True
Sharp means having an edge or a point that can cut or push into another object. True or false?
True
It means acting against something.
opposite
safety precautions is action taken to reduce the risk of accident or injury; they are specific to the experiment and more than just basic laboratory rules. True or false?
True
This is force that is equal and opposite, so their effects cancel out.
balanced
Name the vegetable that looks like an ASTEROIDS.
potato

True
What is the name of the largest ASTEROID?
Ceres
These are objects made from rock that orbit the Sun.
ASTEROIDS

True
The milky way is what we call a SPIRAL galaxy. True or false?
true
