- Forces
- Between Objects
- Objects give equal and opposite forces on each other
- Action and Reaction forces
- Objects give equal and opposite forces on each other
- Measured in NEWTONS
- Resultant Force
- Single force that would have the same affect on the object as all the forces acting together
- Force at zero
- If the object is still, it will stay still
- If the object is moving it will carry on moving at the same speed and same direction
- Not at zero
- Results in acceleration in the direction on the force
- If the object is at rest it will accelerate in the direction of the force
- If already moving in the direction of the force the object will accelerate in that direction
- If the object is moving in the opposite direction of the fore it will decelerate
- If the object is moving it will carry on moving at the same speed and same direction
- Acceleration
- F=m x a
- The greater the Resultant Force on an object the greater acceleration
- Resultant Force
- Single force that would have the same affect on the object as all the forces acting together
- Force at zero
- If the object is still, it will stay still
- Not at zero
- Results in acceleration in the direction on the force
- If the object is at rest it will accelerate in the direction of the force
- If already moving in the direction of the force the object will accelerate in that direction
- If the object is moving in the opposite direction of the fore it will decelerate
- Acceleration
- F=m x a
- The greater the Resultant Force on an object the greater acceleration
- The bigger the mass of the object the more force needed to make the object accelerate
- Resultant Force
- The bigger the mass of the object the more force needed to make the object accelerate
- On the road
- Stopping distance= thinking distance+ braking distance
- Thinking distance increased if driver is tired or under drugs/alcohol
- Braking distance increased by road/weather conditions and car condition
- Between Objects
