Find the mass of an 80 Newton object on the earth.
2kg
6kg
10kg
8kg
Which of the following gives the relationship between the force applied to an un-stretched and the amount the spring is stretched when the force is applied.
Hooke's Law.
Newton's Law.
Charle's Law.
None of these.
Which of the following states that the restoring force of a spring is directly proportional to a small displacement?
Which of the following can change an object's motion in a number of ways?
Weight.
Force.
Time.
An object of mass of 12 kg on the earth would have a mass of 12 kg on the moon. This same object will have a weight of 120 N on the earth and a weight of 20 N on the moon. This difference is due to the fact that
The moon's gravitational attraction is 1/6 of the earth's gravitational pull.
The earth's gravitational attraction is 1/6 of the earth's gravitational pull.
Both A and B.
That which changes or tends to change the state of rest or motion of a body is called:
Gravity
Friction
Weight
Force
Which of the following is a force which can act through space ?
Gravity.
Mass.
Volume.
Density.
Which of the following is the law that shows the relationship between the forces applied to a spring and its elasticity.
Gravity and magnetism are forces which:
Work at a distance
Need to be touching to work
Get stronger the further away they are
Get weaker near things
Electric force between electric charges
Increases with distance.
Decreases with distances.
Remain the same.
