Fragen in diesem Quiz (13)
1What happens to a moving car when there is a resultant force?
- AIt accelerates
- BIt decelerates
- CIt stays the same
2The acceleration of a car depends on..
- Aspeed it was traveling and road surface
- Bair resistance applied and mass of car
- Csize of resultant force and mass of car
3What can an object best accelerate?
- Awhen the force is greater but mass is smaller
- Bwhen the mass is greater and the force is greater
- Cwhen the force is smaller but the mass is greater
4what is newtons second law of motion?
- Aforce (N) = Mass (kg) + acceleration (m/s squared)
- Bforce (N)= Mass (kg) x acceleration (m/s squared)
- Cforce (N)= Mass (kg) - acceleration (m/s squared)
5when investigation force and acceleration what must you keep the same?
- AForce
- BMass
- CAcceleration
6How do you work out Acceleration (m/s squared) ?
- Achange in velocity (m/s) divde by time (s)
- Bchange in velocity (m/s) x time (s)
- Cchange in velocity (m/s) - time (s)
