Preguntas del test (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)
7cyclist accelerates from 0 to 10 m/s in 5 seconds. What is her acceleration?
(acceleration= change in velocity divided by time)- A5m/s sqaured
- B4 m
- C2 m/s squared

10on the moon the gravitational field strength is 1.6 n/kg. What will james (who weighs 70 kg on earth) weight be on the moon?
(Weight= mass x gravitation field strength)- A112n
- B112kg
- C64 n
11As the speed of an object increases the drag on it decreases
- AVerdadero
- BFalso
12in a vacuum all objects fall at the same rate mass does not matter
- AVerdadero
- BFalso
13depending on the mass of the falling objects depends the rate of acceleration
