In physics a force is something that can move an object change its speed or change its direction The unit of force is called the Newton One of the key ideas is that force equals mass times acceleration This means that the heavier an object is the more force you need to move it and the faster you want it to accelerate the more force is required For example it is much easier to kick a football than to push a car There are different types of forces such as gravity which pulls objects toward the gro
