To calculate net force: add vectors in the same direction; subtract vectors in the opposite direction.
To calculate acceleration: acceleration = net force / mass
Use the following abbreviations for units:
newtons = N
meters per second squared = m/ss
Use the following for directions:
right, left, up, down

### What is the net force? (Don't forget to write units and direction!)

Explanation
The net force is 0 N. This means that the forces acting on the object are balanced and cancel each other out, resulting in no overall force. Therefore, there is no acceleration or change in motion of the object.

### What is the acceleration?  (Don't forget to write units and direction!)

Explanation
The given answer states that the acceleration is 0 m/ss. This means that there is no change in velocity over time, indicating that the object is not accelerating. The units "m/ss" indicate meters per second squared, which is the standard unit for acceleration. Therefore, the explanation suggests that the acceleration is zero, with no direction specified.

Rate this question:

• 3.

### What is the net force?

Explanation
The net force is 5 N right because it is the only force acting on the object. Since there are no other forces in the opposite direction, the net force is equal to the given force of 5 N right.

Rate this question:

• 4.

### What is the acceleration?

Explanation
The acceleration is 0.5 m/ss right. This means that the object is experiencing a change in velocity of 0.5 meters per second per second in the right direction. This indicates that the object is gaining speed at a constant rate in the right direction.

Rate this question:

• 5.

### What is the net force?

Explanation
The net force is the overall force acting on an object. In this case, the net force is 10 N down, which means there is a force of 10 N acting in the downward direction. This could be due to the gravitational force pulling the object downward or any other force that is causing it to move in that direction.

Rate this question:

• 6.

### What is the acceleration?

Explanation
The acceleration is given as 0.2 m/ss down. This means that the object is experiencing a downward acceleration of 0.2 m/ss. The negative sign indicates the direction of the acceleration, which is downwards. The unit "m/ss" represents meters per second squared, which is the standard unit for acceleration. Therefore, the object is accelerating downwards at a rate of 0.2 meters per second squared.

Rate this question:

• 7.

### What is the net force?

Explanation
The net force is the overall force acting on an object. In this case, the net force is 30 N left, which means that there is a single force of 30 N acting in the left direction. This force is strong enough to overcome any other forces acting on the object and cause it to move to the left.

Rate this question:

• 8.

### What is the acceleration?

Explanation
The given answer states that the acceleration is 10 m/ss left. This means that the object is experiencing an acceleration of 10 meters per second squared in the left direction. The unit "m/ss" represents meters per second squared, which is the standard unit for acceleration. Therefore, the object is accelerating at a rate of 10 m/ss to the left.
