The document discusses forces, measuring forces, motion, measuring motion, and their relationship. It explains that a force can be a push or pull and is measured in Newtons using a newton meter. Motion is the movement of an object over time and is measured by speed, which equals distance divided by time. A connection between forces and motion is that applying a greater force allows an object to travel a farther distance over the same period of time.
2. Force
A force can be either a pull or a push. If you want to open a closet you
have to apply a force to the closet door for it to open. The same is if you
want to close the closet you have to apply a pushing force to the closet
door for it to close.
We cannot see a force but we can see what the force does. Forces can
change the speed and size of something; if you bend a spoon the size
of the spoon will decrease.
3. Measuring forces
We cannot see a force but that does not mean that we can’t measure a
force. Forces are measured in Newton’s (N), hence Isaac Newton.
We can use a newton meter to measure the amount of Newton’s in an
object. A newton meter has a hook at the end and the hook stretches
when a force is applied. The further the hook stretches the greater
the force.
4. Motion
Motion is the movement of an object and it is described as displacement,
time, velocity, and acceleration.
Motion sickness is when your eyes and ears are sending different messages
to your brain. So if you are in a car and reading a book your eyes are on the
book whereas your ears are listening to the movement of the car this then
makes your feel a bit nauseated and then you throw up. So you listen to the
movement of your car with your ears and you move your eyes to follow the
page of the book.
5. Measuring Motion
Speed is the measurement of motion and speed equals distant
divided by the time taken (S=D/T).
So we can find out the speed of something by dividing distance
and time. Exam questions may ask for you to work out the speed
of something if the distance is 20miles and the time taken is 60
minutes so you have to divide 20 by 60 for you to get the speed.
6. Conclusion
A force can be either a push or a pull. We cannot see a force but we
can see what it does. A force is measured in Newton’s (N) hence
Isaac Newton. the greater the force the bigger the newton.
Motion is the movement of an object. Motion sickness is when
your eyes and ears are sending different messages to the brain.
Motion is measured in speed and speed equals distance divided by
time (S=D/T)
Because motion is the movement and a force is a push or a pull
then these two might have a connection. If there is a car and it is
moving at a steady speed and you give a boost of 100N it will go
very far but if the car is not moving, you will have to give a harder
boost for it to reach that distance.
