Physics Quiz - Motion
 1. The tendency for a stationary object to remain at rest, and for a moving object to continue at the same speed is called:A momentumB frictionC inertia 2. Which vehicle - a motorbike or a truck - would have the greatest inertia?A they are the sameB the motorbikeC the truck 3. If a car brakes suddenly, the first movement of the passengers is to:A continue to move forward at the same speedB be thrown back into the seatC move backwards as the seat belt tightens 4. Rate of movement in a particular direction is called:A momentumB speedC velocity 5. An example of velocity is:A 100 km/hB 100 m/sC 100 m/s up 6. If a skateboarder travels 100 metres in 20 seconds, what is his speed?A 50 km/hB 5 m/sC 2000 m/s 7. A rocket is launched at a speed of 10 kilometres per second. How far will it travel in 1/2 minute?A 300 kmB 5 kmC 3000 m 8. The rate of change of speed is called:A velocityB accelerationC friction 9. What is the speed of a car that is stationary?AzeroBit has no speed, only velocityCinsufficient information given 10. Gravitational acceleration is: Aonly able to calculated on earth Brate of change of speed of falling objects Cis the same on all planets 11. If a car speeds up from a standing start to 100 m/s in 5 seconds, what is its acceleration (in m/s/s)? A500 B4 C20 12. The rule to calculate momentum is: Amass X velocity Bacceleration / speed Cmass X acceleration 13. BAC stands for: ABlood Alcohol Concentration BBlood Alcohol Content CBody Alcohol Concentration 14. Factors which affect the reaction time of the driver are: Aengine power and brake condition Bdriver's age and alcohol consumption Ctyre and road conditions 15. Factors that affect the braking distance of the vehicle are: Aexperience and age of the driver Bage of the engine and suspension Ctyre and road conditions
