these are the questions: 
1.What is speed and what is it measured in? 
2. Caculate the speed of the following: 
A) an object travelling 120 meters in 12 seconds 
B) an object travelling 640 meters in 8 seconds 
3. what is meant by acceleration? 
4. calculate the acceleration of an object if it goes from rest to 50m/s in 10 seconds. 
5. calculation how fast an object would be travelling if it accelerates 6m/s for 8 seconds 
7. what is meant by the word force? what is it measured in? 
8. name 3 things that a force can do to an object. 
9. newtons 1st law is also known as the law of inertia. what does this law mean? 
10. what is the formula that expresses newton's second law? 
11. calculate the force needed to accelerate an object 4m/s/s with a mass of 5kg 
12. calculate the acceleration of a 50kg object if you apply 300 newtons of force to it. 
13. state newtons third law, give an example of it 
14. what are 2 things that effect the strength of gravity to an object? 
15. if you apply a force of 5N to the left side of an obkect and 5N of the right side of the object, what is the overall or net force on the object? 
16. if you apply a force of 5N to the left side of an object and 3N to the right side of an object, what would be the overall or net force on the object? which way would the object move? 
17. convert 15m/s to km/hr 
18. the acceleration due to gravity on earth is 9.8m/s/s. what is the weight of a person who has a mass of 65kg on earth?
