What is a distinction between velocity and acceleration?
The Main Difference Between Velocity and Acceleration Here are the basic definitions of velocity and acceleration: velocity – the rate of displacement of a moving object over time. acceleration – the rate of velocity change over time.
What is the relationship between acceleration and velocity?
Acceleration is the rate of change of velocity. (when velocity changes -> acceleration exists) If an object is changing its velocity, i.e. changing its speed or changing its direction, then it is said to be accelerating. Acceleration = Velocity / Time (Acceleration)
What happens to acceleration when velocity increases?
When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down.
What is the acceleration of a 50 kg object?
A body having mass 50 kg is needed to be accelerated by 3 m/s2.
How many watts does a lift use?
The elevator controller uses about 83 watts all the time, even when the elevator is idle. That’s about $130 per year without even moving! Going up uses almost 40 times as much power as going down. Going up 5 floors uses about 500 kilowatt seconds and costs about $0.03.
How many joules is 1000 watts?
Energy and Power A kilowatt is equal to 1000 watts, so 1 kWh represents the amount of energy transfer that occurs over one hour from a power output of 1000 watts (i.e., joules per second). Thus 1 kWh is equal to 3,600,000 joules of energy transfer (work).
How many joules is 3000 watts?

What two factors affect the rate of acceleration of an object?
The acceleration of an object depends on the mass of the object and the amount of the force applied to it. It states that the acceleration of an object increases with increased force and decreases with increased mass.
Does constant force cause acceleration?
Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
