How do you calculate the force required to move an object at a constant velocity?

Force = Mass x Acceleration. Constant velocity means Acceleration is 0. So for any mass whatsoever, assuming there is no drag or friction, Force = Mass x 0.

Can an object have a speed of zero while it has an acceleration that is not zero?

No. There is no relation between speed and acceleration. Acceleration is the rate of CHANGE of speed, and an object can have any speed at any acceleration.

What is the velocity by which they hit the ground?

Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.

How do you calculate the force of an object moving?

Multiply mass times acceleration. 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.

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

How to find force of friction

1. Choose the normal force acting between the object and the ground. Let’s assume a normal force of 250 N .
2. Determine the friction coefficient.
3. Multiply these values by each other: (250 N) * 0.13 = 32.5 N .
4. You just found the force of friction!

How do you find acceleration with mass?

According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a=Fm. This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

How is velocity zero?

Velocity as a Vector Quantity Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity.

How do you calculate the speed of an object before it hits the ground?

Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m .

How do you find the velocity of an object?

To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. For example, if you traveled 50 miles in 1 hour going west, then your velocity would be 50 miles/1 hour westwards, or 50 mph westwards.

What is the missing variable in the physics equation for force?

This calculator will find the missing variable in the physics equation for force (F = m * a), when two of the variables are known. Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.

What is the relationship between force and Mass in physics?

F = m a Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.

What is the formula for force in physics?

Force Equation F = m a Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.

How do you calculate force from mass and acceleration?

Force Equation. Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.
