## How do you calculate weight force on an incline?

1. The normal force of an object placed on a sloping surface is always perpendicular to the surface.
2. mgsinθ
3. Take g = 9.8ms-2.
4. (a) Σ F = ma = mg sin θ where mg sin θ is the component of the force parallel to the slope.

## How do you calculate the force needed to move an object?

The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration.

## What force is needed to move an object uphill?

Less force is needed to move an object uphill with an inclined plane, but the force must be applied over a greater distance. The mechanical advantage of an inclined plane is always greater than 1, because the machine puts out more force than the user puts into it.

## Is it easier to push or pull uphill?

In pushing,component of force adds up to the body and due to this normal reaction from ground increases resulting in increase in friction. Hence pushing becomes harder compared with pulling. In pulling normal reaction from ground decreases so friction also will be decreased. Therefore pulling is easier than pushing.

## How much force is needed to push an object up an incline?

One of the insights that comes from the setup of this problem is that the force required to push a mass m up a frictionless incline is equal to mgsinθ.

## How much force is required to push an object up a ramp?

You need 660 newtons of force to push the refrigerator up the ramp. In other words, your two friends, who can exert 350 newtons each, are enough for the job.

## How much force is needed in growing up a less steep incline?

How much force is needed in going up a less steep incline? a. less; longerC.

## Why do you need to use force in moving a ball up a ramp?

(1) Force making the ball move up the ramp. (2) Friction Force (fighting against the Force that is moving the ball up the ramp). (3) Gravity – this is the Force all objects will experience if they are on our Earth.

## Which type of force causes the object to remain in place?

Friction is the force between an object in motion and the surface on which it moves. Friction is the external force that acts on objects and causes them to slow down when no other external force acts upon them. Inertia is the tendency of a body in motion to remain in motion.
