an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force

• Newtons 1st law

• Newtons 3rd law

• Newtons 2nd law

How will the object act in response to these forces?

• The object will move upward and toward the right.

• The object will move to the right only.

• The object will move upward only.

• The object will remain at rest.

Moving a dresser you push on it 900N westwards, while Friction pushes 600N eastwards, the Fnet then would be...

• 300 N East

• 900 N West

• 1500 N West

• 300 N West

Moving a dresser, you push on it with 900N westwards, while friction pushes 600N eastwards. The net force and direction would be...

• 300 N East

• 900 N West

• 1500 N West

• 300 N West

Answer explanation

To find the net force (Fnet), subtract the friction force (600N east) from the applied force (900N west). Fnet = 900N - 600N = 300N west. Thus, the correct answer is 300 N West.

The diagram below shows a skateboarder pushing himself forward with a force of 25 N while the wind pushes back with a force of 5 N. How will the skateboarder be affected if the force of the wind increases to 8 N?

• The speed of the skateboarder will increase.

• The speed of the skateboarder will remain constant.

• The speed of the skateboarder will decrease.

• The skateboarder will come to a stop.
