Question: What Affects Acceleration Due To Gravity?

How do you make an object stable?

There are two ways of making an object more stable.

One way is to lower its centre of gravity.

Racing cars have very low centres of gravity, so that they are less likely to roll over enven when cornering at high speeds.

The other way is to make the base of the object wider..

Does acceleration increase with height?

The acceleration of an object changes with altitude. The change in gravitational acceleration with distance from the centre of Earth follows an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth.

What two factors will make an object stable?

The stability of an object is dependent on two factors:The base width of the object.The center of gravity.

Does acceleration depend on direction?

Since acceleration is a vector quantity, it has a direction associated with it. The direction of the acceleration vector depends on two things: whether the object is speeding up or slowing down.

Does acceleration depend on the speed of an object?

That’s because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction. … Acceleration occurs anytime an object’s speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous.

Why is acceleration due to gravity negative?

The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. … The acceleration is negative when going down because it is moving in the negative direction, down.

What are the factors that affect the acceleration due to gravity?

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

What are the factors influencing acceleration?

He observed that the acceleration of an object depends on the mass of the object and the size of the force applied to it. states that the acceleration of an object increases with increased force and decreases with increased mass.

What is acceleration due to gravity class 9?

When an object falls freely towards the surface of earth from a certain height, then its velocity changes. This change in velocity produces acceleration in the object which is known as acceleration due to gravity denoted by letter g. The value of acceleration due to gravity is g= 9.8 m/s2.

Is gravity an acceleration?

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). … It is known as the acceleration of gravity – the acceleration for any object moving under the sole influence of gravity.

How does acceleration due to gravity?

Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth. … From the above equation, it is clear that acceleration due to gravity is more at equator and less at poles.

Where acceleration due to gravity is maximum?

Where, g is the acceleration due to gravity on the surface of the earth. g’ = g Thus acceleration due to gravity is least at the equator and maximum at the poles.

Where acceleration due to gravity is zero?

So, acceleration due to gravity is zero at the centre of the Earth.

How Does height affect Centre of gravity?

The position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed. … The higher the centre of gravity the more likely an object is to topple over if it is tilted.

Does acceleration due to gravity change?

When objects fall to the ground, gravity causes them to accelerate. … Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2, so by 1 second after an object starts falling, its velocity is 9.8 m/s.

What happens to acceleration when force is increased?

As we increase the force on an object the acceleration increases proportionally. 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.

What makes a structure stable?

A structure is stable if forces are balanced. Unbalanced forces can cause stress and fatigue in structures. Proper materials can be used to stabilize structures. Building techniques can be used to stabilize structures.
