Answer: An object's motion can be changed by unbalanced forces. Balanced forces do not change the motion of an object.
The motion of an object acted on by a force depends partly on the strength of the push or pull. The stronger the push or pull, the faster the object will move. For example, the father in the picture below is pushing his daughter in a swing. When he uses more force to push, the swing moves higher.
Explanation:
To show motion on a graph you draw the path of where the object has gone
Answer:
(a)
(b)
Explanation:
For Part(a)
Apply ∑Fy=ma
Solve for a
For Part(b)
Assume the maximum acceleration (maximum tension upwards is greater than the weight of the chain+boulder)
As the given data
Using equation of simple motion
You use the equation potential energy= mass x gravity x height. 10x2x9.8=196.
Answer:The Taller one
Explanation: Air drag(friction) also known as air resistance,the opposing force acting against the force of gravity, if a falling Object have a high air drag it will mean the object have a high air resistance. The higher the air resistance the higher the impact of the force of gravity on an object. The force of gravity will act to want to overcome the opposing force in order to bring the Object or the taller person down.
