How can you decide an object is moving faster or slower?

How can you decide an object is moving faster or slower?

Answer: In simple words, the distance covered by an object in a fixed interval of time helps you know whether the object is moving fast or slow. The object that shows fast motion is said to have a higher speed while the one with slow motion is said to have a slow speed.

How do you know which object is faster?

Speed is the rate at which an object’s position changes, measured in meters per second. The equation for speed is simple: distance divided by time. You take the distance traveled (for example 3 meters), and divide it by the time (three seconds) to get the speed (one meter per second).

Which of the following helps us to decide which one is moving faster than other?

Answer: Relative Velocity of object helps us to decide which one is moving faster than the other.

What does the distance moved by an object in unit time indicate?

speed of
The distance covered by an object in a unit time is known as the speed of the object.

What causes faster motion or slow motion?

Friction can slow things down and sometimes make things go faster because of the grip that it causes. STATIC FRICTION is the force that will resist the movement up until it is overcome by a greater force and the motion occurs.

How can we say that the speed of an object is faster than the other Class 7?

Answer: If an object covers more distance in equal intervals of time with respect to other, then we can say that object is moving faster with respect to the other object.

How can we change the speed and the direction of a moving body?

WE CAN CHANGE THE SPEED AND THE DIRECTION OF A MOVING BODY OR A MOVING OBJECT BY APPLYING FORCE ON THAT MOVING BODY OR MOVING OBJECT.

What is the correct relation for speed?

It determines how fast the movement of the object is. It is scalar , and it has no direction. Higher speed only signifies the fastness of the object whereas lower speed implies the slowness. Speed = distance / time is the correct option.

How can you make an object accelerate faster?

LAW 2 – Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.

Which allows us to decide whether an object is moving faster?

The thing which allows us to decide whether an object is moving faster than other is their speed and time taken to cover equal amt of distance in given time. We can decide whether a object is fast or slow only when we compare it’s speed and distance traveled with one or more bodies

Does force always change the state of motion of an object?

Answer: No, it does not always change the state of motion of an object. 17. What is muscular force? Answer: The force resulting due to the action of muscles is known as muscular force. 18. Give two examples of muscular force. Answer: Bending of our body and kicking the ball. 19. Does the force can change the speed of a moving object? Answer: Yes.

How do fast objects know how fast they are going?

As far as the fast object is concerned, time passes at the same rate as always. This is because there is no absolute state of rest … or, put another way, there is no way for an object to know how fast it is going. It can tell how fast it is passing another object – but it could just be that the other object is passing it.

Do forces applied on an object in the same direction add together?

Answer: Forces applied on an object in the same direction add to one another. 7. What will be the resultant force when two forces act in opposite directions on an object? Answer: When two forces act in opposite directions on an object then the net force will be the difference between two forces.
