Forces make things move or stay still by.....

What are the two types of push and pull forces?

When a person jumps out of an airplane, is that a contact or non-contact force?

What happens to an object when forces are unbalanced?

What is a balanced force?

Is magnetism a contact or non-contact force?

What are the two ends of the magnet called?

True or False: All magnets are man-made.

What happens when you have a north pole and a north pole of a magnet together?

Fill in the following blanks:

Magnets create a _____________ around them. We cannot see these forces but they attract objects made of _______ and _________.

True or False: All masses have gravity

Which one of these conclusions from Newton are correct? 1.) Small masses pull big masses towards them. 2.)The bigger the mass, the stronger the pull 3.) The farther the mass, the stronger the pull

Who discovered gravity and when?

Is the weight of a kangaroo higher on the moon or the earth? Why?

What would happen if the Earth did not have gravity?

True or False: Upthrust is a contact, push force applied by water and air

Who discovered upthrust?

A bird flying is an example of upthrust? Why or why not?

Which would fall slower if dropped from a building, a piece of paper or a mobile phone? Why?

Why does a rubber duck float and a metal duck sink?

Tennis uses (contact/non-contact) forces to move the ball

True or False: Players use a raquet to apply pull forces to the ball

Push force makes the ball change___________.

Does a big push force make the ball speed up or slow down?

Players move about by applying the push forces to the ___________ with their legs and feet.

pushing or pulling

Contact and non-contact forces

non-contact force

it can make an object start moving, speed up, slow down, change direction or stop

When two forces applied to the table are opposite and equal

non-contact

North Pole and South Pole

False: some magnets are natural, for example mineral magnetite

They repel

magnetic field, iron, steel

Magnets create a magnetic field around them. We cannot see these forces but they attract objects made of iron and steel.

True

#2 is correct, The bigger the mass, the stronger the pull

Isaac Newton over 300 years ago

The kangeroo would have a higher weight on the earth because the force of gravity is higher.

Our belongings and us would float away

True

Archimedes, an ancient greek scientist

Yes, a bird flying has upthrust from air and and is pulled down by gravity due to its weight

A piece of paper would fall slower because it has a small mass and big volume

A rubber duck has balanced forces (weight of the duck=upthrust). A metal duck has unblanced forces (weight> upthrust)

contact

False; they apply push forces

direction

speed up

ground
