You can describe the motion of an object by its position, speed, direction, and acceleration.
How would you describe the object’s motion given that its velocity increases by the same amount every time?
If an object travels in a straight line and its velocity increases or decreases by equal amounts in equal intervals of time then the acceleration of the object is said to be uniform.
What can you say about the motion of an object?
What can you say about the motion of an object if its speed – ‘time graph is a straight line parallel to the time axis? Answer: If speed time graph is a straight line parallel to the time axis, the object is said to be moving uniformly.
What are three ways that an object can change its velocity?
Acceleration is the rate of change in the velocity of an object. Velocity can change in three different ways. Speed up, slow down, or changing direction. All three of these changes are technically called acceleration.
What does speed tell you about an object’s motion?
Speed is a description of how fast an object moves; velocity is how fast and in what direction it moves. In physics, velocity is speed in a given direction. When we say a car travels at 60 km/h, we are specifying its speed. When we say a car moves at 60 km/h to the north, we are specifying its velocity.
What can you say about the motion of an object whose distance-time?
What can you say about the motion of an object whose distance-time graph is a straight line parallel to the time axis? When the slope of the distance-time graph is a straight line parallel to the time axis, the object is at the same position as time passes. That means the object is at rest.
What can you say about the motion of an object whose distance-time graph is straight line passing through the origin making an angle from the time axis?
(b) a straight line passing through the origin making an angle from the time axis.When the distance-time graph makes an angle with the time axis it means the object is moving at a constant speed in a straight line. The slope of the graph gives the speed of the object.
What can you say about the motion of an object whose velocity time graph is a straight line parallel to time axis?
Answer: The velocity time graph of the object is a straight line parallel to the time axis.Thus, the motion of the object is uniform. So, the object is undergoing uniform motion.
What affects velocity?
Air resistance and drag force affect the object’s movement and velocity, relative to its shape.Other elements include velocity, the shape and surface area of the object, drag force, and the angle at which the object is thrown.
What makes a change in velocity?
A change in direction causes a change in velocity . This is because velocity is a vector quantity – it has an associated direction as well as a magnitude. A change in velocity results in acceleration , so an object moving in a circle is accelerating even though its speed may be constant.
How do you determine velocity?
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 causes an object to move or accelerate?
Acceleration and velocity
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.
Why is distance insufficient to determine an object’s location relative to another object?
Why is distance insufficient to determine an object’s location relative to another object?-Distance is not enough information to determine the location of an object. If describing the location, the direction or relative to the starting point is vital to determining location.
What two things must you know to determine speed?
Chapter 19 – Motion
| Question | Answer |
|---|---|
| What two factors determine speed? | distance & time |
| What is the difference between speed and velocity? | Velocity has direction speed does not. |
| What best represents acceleration as presented on a graph? | velocity change vs. time |
| What is force? | a push or pull acting on an object. |
What can you say about the motion of an object whose distance time graph is a straight line parallel to the time axis Brainly?
If the distance-time graph is a straight line parallel to the time axis, it indicates that with the development of time the body is solid at one point. That shows that the object is at relaxation.
What is the motion of an object whose distance time graph is a straight line passing through origin?
When the distance-time graph makes an angle with the time axis it means the object is moving at a constant speed in a straight line. The slope of the graph gives the speed of the object.
What does the inertia of a moving object depends on?
The inertia of a moving object depends on the mass of the object. The heavier the item, the Heavier is its tendency to resist the change in state of motion.Mass is the quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has.
What would you infer if distance time graph is straight?
A straight line on distance-time graph indicates that the object is moving at steady (uniform) speed.
What is the nature of the distance time graph for uniform and nonuniform motion of an object?
For uniform motion of an object, its distance-time graph is a straight line with constant slope. For non-uniform motion of an object, its distance-time graph is a curved line with increasing or decreasing slope.
What does the path of an object look like when it is in uniform motion?
The path of an object in uniform motion is a straight line. Uniform Motion:If a body travels in a straight line and covers an equal amount of distance in an equal interval of time, then it is said to have uniform motion.
What can you say about the motion of a body if its velocity time graph is a straight line?
(i) The body has a uniform velocity, if the velocity-time graph is a straight line parallel to the time-axis. (ii) If the velocity-time graph is inclined to the time-axis at certain angle, the body has uniform acceleration.
