a rowing boat is being pulled to shore by two people with a force of 30 N each. A force of 10 N is resisting the movement in the opposite direction. what is the resultant force on the boat?
(30 + 30) - 10 = 50 N towards the shore
1 of 6
what is the resultant force on the body moving at constant velocity?
0 N
2 of 6
what happens to the acceleration of a body if the resultant force on it is doubled?
the acceleration also doubles
3 of 6
in which direction does friction act on the body - with or against the bodies motion?
against motion
4 of 6
what happens when a force is acting on a object?
it causes the object to change shape, to start moving, to stop moving, to accelerate or to decelerate
5 of 6
What happens when 2 objects interact with each other?
They exert a force on each other, the forces are equal in size but opposite in direction
