# Can an object move if the net force is zero?

## Can an object move if the net force is zero?

Newton’s First Law of Motion An object’s velocity (a vector) does not change if and only if the net force acting on the object is zero. In other words, if there is no net force on an object, its speed and direction of motion do not change (including if it is at rest).

Can an object move without net force?

So, yes, the object can be moving when there is no force applied to it. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

How does increasing the mass affect acceleration?

Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration. If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

### What is the net force that acts on a 10 n freely falling object?

The ratio of force to mass for free falling objects is equal to the force of gravity ‘g’ which at the surface of the earth is equal to 9.8 m/s2. What is the net force that acts on a 10-N freely falling object? The net force acting on a 10 N free falling object is 100 N (98 N to be precise).

Does a heavy parachutist fall faster than a lighter one?

It has to be remembered that while the air resistance on each parachutist is the same, the gravitational force on the heavy person is greater than that on the light person so in a falling situation, it takes longer for the heavy parachutist to reach terminal velocity and, as a consequence, will be falling at a faster …

Will parachutes fall faster or slower if the person or weight is heavier?

2. Well, yes and no: what matters is the size, shape, and weight of the parachute. So if you have two parachutes with the same size and shape but made of different materials, one heavier than the other, the heavier parachute will fall faster.

#### Do heavier people fall faster when skydiving?

In short: when you skydive, your surface area slows you down, and your mass speeds you up. That’s why small skydivers sometimes wear weights. Someone the same height as you but heavier will have increased mass, and fall faster.

Will 2 objects fall same speed?

If you neglect air resistance, objects falling near Earth’s surface fall with the same approximate acceleration 9.8 meters per second squared (9.8 m/s2, or g) due to Earth’s gravity. So the acceleration is the same for the objects, and consequently their velocity is also increasing at a constant rate.

Does a feather and a rock fall at the same speed?

Spoiler: the answer is that they will all fall at the exact same rate. Though some objects, like feathers, seem to fall slower because of air resistance. In order to see the true nature of gravity effecting the feathers, you need to remove all the air in the room.
