Free Body Diagrams & Net Forces practice

Front

Are the net forces of this object at equilibrium?

Back

Front

If this box's net forces are at equilibrium, is it possible that the box could still be in motion?

Back

Yes, if it was originally in motion when these forces were applied. Since the net force equals zero, there would be no change in motion.

Front

Assuming this object was originally at rest, will the net force cause an acceleration, (a change in its motion)? If so, in what direction will it accelerate?

Back

The forces are not balanced, so the Net force is not in equilibrium, so the box will accelerate down.

Front

What is the magnitude of the force causing the box to accelerate? What direction will it accelerate?

Back

Front

This box is originally traveling at a velocity of 25m/s out of the screen (z axis). What is the magnitude of the net force acting on this box, and what direction will the net force cause the box to accelerate?

Back

Front

What is the magnitude of the normal force?

Back

Front

What is the equation for the force of gravity?

Back

Fg=mg

Answer explanation

we need to be more specific about what type of acceleration we are using in the equation as there is the x component of acceleration, and there is the y component, which is the acceleration due to gravity. 

Front

Calculate the force due to gravity vector component.

Back

-9800 N

Answer explanation

Fg=mg,  Therefore..
Fg = (1000)(-9.8)
Fg= 9800 N
