What causes to move?
Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity). Friction is the force between two objects in contact with each other that will resist an attempt to move them.
Which among the object is the hardest to move?
Answer: The greater the weight (or mass) of an object, the more inertia it has. Heavy objects are harder to move than light ones because they have more inertia.
What causes an object to stay in place?
An object will stay in place until a force sets it in motion. The pull of gravity is a force that might set an object (or a skier) in motion. The force you exert with your legs or arms can set a ball in motion. An object will continue to move until a force slows or stops it.
What is the evidence that the object moved?
Answer: The object’s motion can then be observed and/or measured to provide evidence of a trend that can be used to forecast potential motion. Explanation: Things can shift, change shape, and speed up or slow down due to force.
What happens when two objects collide?
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
Can objects move on their own?
Objects do not move on their own. If they are in motion they were initially moved by a force, either from their initial development as an object or by an outside force that initially moved them to motion. Yet, the atoms and smaller particles of objects are always in motion.
What is it called when a force makes an object move away?
repulsion. noun. physics an electrical or magnetic force that makes things move away from each other.
Is force needed to keep a moving body in motion?
An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. In the absence of any forces, no force is required to keep an object moving.
What is the force required to stop a moving object?
Explanation: an external force is required to stop a moving object because the external force creates a sort of friction or a blockage for the moving object helping it to stop.
What is an example of a force causing an object to start moving?
If you throw a ball, you are pushing on it to start its movement. If you drop an object, the force of gravity causes it to move. If an object is initially stationary, it accelerates when it starts to move. Acceleration is the change in velocity over a period of time.
What 3 things can a force change?
A force can do one of four things to an object:
- Make it speed up – accelerate.
- Make it slow down – decelerate.
- Change its direction.
- Change its shape.
