Q & A: Acceleration, Velocity, Distance, Time The basic equation for solving this is: d = vt + (1/2)at2. where d is distance traveled in a certain amount of time (t), v is starting velocity, a is acceleration (must be constant), and t is time. This gives you the distance traveled during a certain amount of time. If you know any 3 of those things, you can plug them in to solve for the 4th.

UNChem Glossary Measure of how fast velocity is changing, so we can think of it as the change in velocity over change in time. The most common use of acceleration is acceleration due to gravity, which can also appear as the gravitational constant (9.8 m/s2). Back to top.

ESSENT IAL P H Y SICS Par t 1 In the special case where the velocity is constant (that is, constant speed in a straight line), this can be simplified to v = s / t {\displaystyle v=s/t} . The average speed over a finite time interval is the total distance travelled divided by the time duration.

Error Propagation Example: Measure the constant velocity of a cart rolling on a 50.0 cm track. The time is measured to be 1.32 seconds with an uncertainty of 0.06 seconds. Since the velocity is the change in distance per time, v = (x-xo)/t. Setting xo to be zero, v= x/t = 50.0 cm / 1.32 s = 37.8787 cm/s.

Acceleration If the velocity of an object changes at a uniform rate, then the acceleration that causes the change in velocity is called uniform acceleration or constant acceleration. For example, the force of gravity imparts an acceleration uniformly which is called acceleration due to gravity.

- Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this: We have distance/time2, or d/t2. Distance is commonly measured in meters, and time in seconds.

Definitions &Translations To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed.

- Speed is the distance an object travels per unit of time. Speed can be expressed as kilometers per hour (km/hr), meters per second (m/s), and so on. In most cases, objects don’t travel at a constant speed. Therefore, the average speed is used to describe the motion. s = speed, t = time, and d = distance. Acceleration is the rate at which an object’s speed changes. Acceleration can be expressed as meters per second per second (m/s/s or m/s2). Forces such as gravity, air resistance, and friction can cause an object to decelerate (decrease speed over time).

The Value of g where d represents the distance from the center of the object to the center of the earth. In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

Glossary of Physics Terms Acceleration due to gravity The acceleration produced in a body due to the earth's attraction is called acceleration due to gravity. It is denoted by the letter g. Its SI unit is m/s². On the surface of the earth, its average value is 9.8m/s². The value of g on the surface of the earth increases in going towards the poles from the equator. The acceleration due to gravity of the earth decreases with altitude and with depth inside the earth. The value of g at the center of the earth is zero.

A car travels due east with a speed of 50 km/h. Raindrops are falling at a constant speed vertically...? Best Answer: Let: u be the vertical velocity of the rain with respect to earth, v be the velocity of the rain relative to the car. To find v, add to u a velocity which would reduce the car to rest. That velocity is a velocity west of: 50 km/hr = 50 / 3.6 m/s.

MP02: Motion Diagrams See Answer Since the velocity is constant, the acceleration and the net force are 0 m/s/s and 0 N respectively. The Fgrav can be calculated from the mass of the object. Fgrav = m • g = (5 kg) • (9.8 m/s/s) = 49 N The object moves at constant speed; thus, the horizontal forces must balance.or this reason, the net force is 35.4 N. Knowing F net, allows us to determine the acceleration of the object: The acceleration of an object is the velocity change per time. For an acceleration of 3.5 m/s/s, the velocity change should be 3.5 m/s for each second of time change.

How can a body have acceleration when its velocity is zero? The acceleration experienced by the ball while in the air is constant, it never changes. This is because the acceleration caused by gravity is constant at 9.8 m/s/s. When the ball reaches the apex of its height for a brief moment it has a velocity of 0. This is despite the acceleration which has been constant.

- If an object goes from an initial velocity to a final velocity, undergoing constant acceleration, you can simply average the two velocities this way. This is particularly helpful and easy to use if you know that it starts with zero velocity (just divide the final velocity in half).

Instantaneous Acceleration When velocity is constant for a particular period of time then the object is in constant acceleration position. If we talk about one dimension, the rate at which objects get slower speed or speed up is equal to the acceleration. In case of instantaneous acceleration, it is the change at a particular moment.

What is the type of acceleration that occurs when an object travels at a constant speed in circular motion? Although there is no change in speed, there is a force and hence (by Newton's second law) an acceleration necessary to keep the object traveling in a circle. Mathematically, it is equal to v^2 / r or equivalently the velocity squared divided by the radius of the circle. Source(s):
