FORCE AND MOTION Section 1 Review Questions
Terms in this set (7)
Describe two forces that would change the motion of a bicycle traveling along a road.
Two forces that would change the motion of a bicycle along a road would be gravity and thermal energy because the gravity is what allows the bike to go down hills or stay on its track and thermal energy would affect its motion when stopping
Can there be forces acting on an object if the object is at rest? Must there be an unbalanced force acting on a moving object?
There can be forces acting on an object if the object is at rest like gravity. There must be an unbalanced force acting on a moving object because if the object would not move then it is a balanced force.
Why does coating surfaces with oil reduce friction between the surfaces?
Coating surfaces with oil reduce friction between the surfaces because it is like when lubricating a machine, it makes it run or it makes it become smoother.
What is the difference between the mass of an object and the objects weight
The mass of an object is a measure of the amount of matter an object contains while an objects weight is the gravitational force exerted on an object in in the objects weight.
Suppose Earth's mass increased but Earth's diameter did not change. How would the gravitational strength near Earth's surface change?
The gravitational strength of the Earths diameter wouldn't be as strong if the Earths mass increased and the diameter stayed the same.
On earth, what is the weight of a large screen TV that has a mass of 75 kg?
Fg= 75 kg x 9.8N/kg
Fg= 735 N
Two students push on a box in the same direction, and one student pushes in the opposite direction. What is the net voce on the box if each student pushes with a force of 50 N?
50+50-50= 50 N would be needed to push the box.
