1. Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it.
2. Force is equal to the change in momentum (mV) per change in time. For a constant mass, force equals mass times acceleration. In this law the direction of the force vector is the same as the direction of the acceleration vector.
The relationship between an object's mass, its acceleration, and the applied force.
F= m * a
3. For every action, there is an equal and opposite re-action.
The laws of motion take place in all situation on all objects.
The Saskachewan Curriculum requiers the intorduction to motion in grade two's physical science providing the foundation for further development build onto it.
|MP2.2||Investigate factors, including friction, which affect the motion of natural and constructed objects, including self. (SI)|
|FM5.1||Analyze the effects of gravitational, magnetic, and mechanical forces, including friction, on the movement of objects. (CP, SI)|
The mind map below demonstaights interactions and applications of the three laws.
