## What is the net force acting on a 1 kg ball moving at a constant velocity?

Students need to notice that a constant velocity means that the acceleration of the object is zero, which in turn means that the net force acting on the object is zero.

### What is the net force if the object keeps moving with the same speed and direction?

Uniform Circular Motion and Net Force: The net force is always in the same direction as the acceleration. For objects moving in circles at constant speed, the net force is directed towards the center of the circle about which the object moves. Such a direction is described as being centripetal.

**What is the magnitude of the net force acting on the object?**

The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.

**What is the net force in figure?**

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

## What is the net force acting on a 1 kg ball in free fall What is the net force if it encounters 2 N of air resistance?

So the net force acting is going to be the force of gravity minus the drag force. This will be 9.8 newtons minus two newtons For 7.8 Newton’s. So the net force is going to be 7.8 newtons as it is a falling downward.

### What is the net force acting on a 1 kg ball in free fall quizlet?

What is the net force acting on a falling 1 kg ball if it encounters 2N of air resistance? 2), which is equal to 10 N. Air resistance is a force in the opposite direction to a falling weight so the net force acting on the ball is 10 N – 2 N = 8 N.

**How do you find the net force of a moving object?**

The net force can be calculated using Newton’s second law, which states that F = ma, where:

- F is the net force.
- m is the mass of the object.
- a is acceleration.

**What is direction of net force?**

According to the modified law of the newton, The direction of the net acceleration for an object is towards the direction of the net force. The net force is the product of the mass of the object and the acceleration produced due to this force.

## What is the direction of net force acting on the object?

The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed. The acceleration of an object is parallel and directly proportional to the net force acting on the object, is in the direction of the net force and is inversely proportional to the mass of the object.

### How do you calculate the magnitude of the net force?

to find the magnitude of the net force, giving you 102 N. Use the magnitude of the force and the mass to find the magnitude of the acceleration: a = F/m = (102 N)/(100 kg) = 1.0 m/s2.

**How do you find the horizontal force?**

There are two horizontal forces – friction and the applied force. The net force can be determined from knowledge of the mass and acceleration of the sled. Fnet = m • a = (4.52 kg) • (1.28 m/s/s) = 5.7856 N, right.

**How does friction affect the speed of an object?**

Once an object is moving, there are fewer points of contact (fewer molecules adhering), so less force is required to keep the object moving. At small but nonzero speeds, friction is nearly independent of speed. Figure 6.10 Frictional forces, such as →f, always oppose motion or attempted motion between objects in contact.

## What is the difference between static friction and kinetic friction?

If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, friction slows a hockey puck sliding on ice. When objects are stationary, static friction can act between them; the static friction is usually greater than the kinetic friction between two objects.

### What is the coefficient of kinetic friction for moving a crate?

If the coefficient of static friction is 0.45, you would have to exert a force parallel to the floor greater than to move the crate. Once there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only keeps it moving at a constant speed.

**How does the magnitude of static friction affect the applied force?**

The magnitude of the static friction balances that of the applied force. This is shown in the left side of the graph in (c). (b) At some point, the magnitude of the applied force is greater than the force of kinetic friction, and the block moves to the right.
