What is a force?
A force can change the speed of an object, the direction of an object and its shape.
1 of 7
What are the three forces?
The three forces are push, pull and twist.
2 of 7
What is the direction change?
Objects change direction if a force is bigger in one direction than the other, for example: a gust of wind blowing a pirate ship off course
3 of 7
What happens when a force acts upon an object?
Objects are deformed when forces act upon them, that is to say they change form or shape. Forces sometimes cause objects to get bigger, for instance, stretching a rubber band. Objects can also become shorter such as when crushing an aluminium can.
4 of 7
What is Newtons 1st law of motion?
An object at rest will remain still until pushed upon by an unbalanced force. An object in motion continues to move with the same speed and in the same direction unless pushed upon by an unbalanced force.
5 of 7
What is Newtons 2nd law of motion?
A force applied to an object will change it's speed in the same direction as the force. A change in speed is called acceleration and the amount of acceleration depends on the strength and force.
6 of 7
What is Newtons 3rd law of motion?
For each force there is another force pushing against it in the opposite direction with the same strength.
