Q&A for How to Calculate Acceleration

SI units are standardized units that are used internationally in scientific writing. When describing acceleration, use the SI units meters per seconds squared (m/s^2).

If you know that acceleration is constant, you can solve for it without time if you have the initial and final velocity of the object as well as the amount of displacement. Use the formula v^2=u^2+2as where v is the final velocity, u is the initial velocity, a is acceleration, and s is displacement. Solve for a to find acceleration.

Yes. If the object is not moving, or is moving at a constant speed in a straight line, the acceleration is zero.

The equation or formula for velocity is similar to the one for speed. To figure out velocity, you divide the distance by the time it takes to travel that distance, and then you add your direction to it.

The formula is final velocity - initial velocity / time. The final velocity is 10 m/s, because the body's final movement as we know is 10m/s. The initial velocity is 0 m/s, because it states, "A body starts from rest." 10 m/s - 0m/s / 2 s, eventually you'll get 5 m/s/s.

Calculating the normal force here, you will only need the mass and angle of inclination of this surface. When placing the X-axis on the ramp of your free body diagram and if the only force acting on your object of 10kg is gravity of Earth, then looking at the Y-axis of your diagram, you should see that that normal force is equal to the Y-component of the gravitational force. Considering the angle given, you should see the normal force is equal to (mass * gravityAcceleration * sin(15)).

Acceleration: F = ma; 18 = 4a; a= 4.5. Velocity (how fast): V[final]= V[initial]+at. Since the object starts at rest, the V[initial] is zero. V[final] = (4.5)(5). Velocity = 22.5 m/s. Distance (how far): D = vt; D = (22.5)(5); D = 112.5 m.

Acceleration is defined as the change in velocity over time. For example, consider a car accelerating from a stoplight to 60 mph. Its initial velocity is zero, but over a time of several seconds, its velocity increases until it reaches 60 mph. If the car remains at 60 mph without changing velocity, then its acceleration would be zero, or zero change in velocity over time.

Net force is the sum of all the forces acting on an object. For example, the net force of two people pushing a box the same direction would be the sum of the force exerted by each person. The same goes for two people pushing against each other, but one force will be negative.

Convert the distances to meters and the times taken to seconds for both and apply the formular distance/time taken, add your answers and divide by two.

Throwing a ball into the air (the acceleration becomes negative as it approaches its height of potential before falling and it slows down). Or a car decelerating.

No; mass is the amount of space an object takes up. Weight is the amount of gravitational pull on an object.

You just subtract the final velocity from the initial velocity (which may be 0 if not given in the problem), then you divide by the time given.

At rest, initial velocity is zero. Use the formula v = u + at, where v is the final velocity, u being the initial velocity.

Acceleration equals delta velocity divided by delta time. Now, any delta quantity equals the final value for the quantity minus the original value for the quantity. So, delta velocity, or change in velocity, equals the final velocity minus the original velocity.

To find initial velocity, start by multiplying the acceleration by the time. Then, divide that number by 2 and write down the quotient you get. Next, divide the distance by the time and write down that quotient as well. Finally, subtract your first quotient from your second quotient to find the initial velocity.

You can't. You need to know two of the three variables.

You can do so by using the formula "a =v/t" when velocity and time are given, or "a=f/m" when force and mass are known.

You use the first method. Delta V is 1.5 m/s - 1.8 m/s. Delta t is 180 s - 0 s. Now just plug the values in the formula.

Acceleration can be zero if the object is not moving or is moving at a constant (unchanging) speed in a straight line. Changing direction counts as acceleration.

A = [1/2m(9.8 m/second^2)] / t^2.

She is not accelerating because she is running at a uniform velocity.

I'm assuming you're asking whether or not mass is a factor in calculating these variables. Weight and mass are not quite the same thing, but that's another topic. Mass is related to acceleration by Newton's 2nd law: F=m*a, so an increased weight decreases acceleration, which means the amount of gained velocity per second is also decreased.

You can't. F = ma requires the presence of force to cause acceleration. Acceleration is a component of force. Without acceleration, then mass x acceleration cannot exist, so force cannot exist.

If you are using speed in MPH, multiply the speed by 1.46. To get speed from velocity...divide MPH by the 1.46 figure.

First calculate the truck's velocity: v=s/t= 400/20 = 20 m/s. If the car is at constant acceleration, you can simply apply a=v/t= 20/20 = 1 m/(s^2).

If they are parallel but opposite directions, then the forces in one direction will be positive and the opposing negative. Then you find the sum.

We can use the following kinematic equation to solve for the acceleration of the car: d = (1/2)at^2 + v₀t, where d is the distance traveled by the car, a is the acceleration of the car, t is the time taken, and v₀ is the initial velocity (which is 0 in this case). Substituting the given values, we get 277m = (1/2) a (9.6 s)^2. Solving for a, we get a = 277 m / (1/2) / (9.6 s)^2. a ≈ 3.28 m/s^2. Therefore, the acceleration of the car is approximately 3.28 m/s^2.

To calculate the acceleration of the ball, we can use Newton's second law of motion, which states that the net force acting on an object is equal to its mass multiplied by its acceleration. So, in this case, the force acting on the ball is 16 N, and the mass of the ball is 0.40 kg. Therefore, the acceleration of the ball can be calculated as: Acceleration = Force / Mass = 16 N / 0.40 kg = 40 m/s/s. So the acceleration of the ball is 40 meters per second per second.
