- Newtons First Law
- Definition
- A FORCE is NECESSARY to CHANGE the STATE of REST or of UNIFORM MOTION in a STRAIGHT LINE of a body
- Summarised
- A force is needed to change uniform motion
- Summarised
- A FORCE is NECESSARY to CHANGE the STATE of REST or of UNIFORM MOTION in a STRAIGHT LINE of a body
- Motion of Bodies
- Stationary/ Moving with a constant velocity
- Net Force = 0
- Net Force 0< needed to move body
- Changing direction of body
- Changing direction requires force to change velocity
- To change velocity, acceleration is involved
- Changing direction requires force to change velocity
- Slowing Down/ Speeding Up
- Need NET force in either direction, or opposing direction of motion. Causing Acceleration.
- REMEMBER: Acceleration can be positive and negative as can any VECTOR QUANTITY
- Vector quantities have BOTH SIZE and DIRECTION
- REMEMBER: Acceleration can be positive and negative as can any VECTOR QUANTITY
- Need NET force in either direction, or opposing direction of motion. Causing Acceleration.
- Stationary/ Moving with a constant velocity
- Key Terms
- Net/ Resultant (Force)
- Sum of the (Force) VECTORS
- Net/ Resultant (Force)
- Remember!
- There are only 3 TYPES of forces OUTSIDE of the NUCLEUS of an ATOM
- Gravitational
- Electrical
- Magnetic
