# What needs force to move?

## What needs force to move?

It explains that an object’s motion depends upon its mass and the amount of force needed to move that mass. An object has inertia whether it is at rest or in motion. In either case, a force must overcome that inertia. The force may create motion, stop it, or change its direction.

## Do you need more force to move an object?

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.

Would you need more or less force to move it?

A net force is required to move any object. The more mass an object has, the more net force is required to make it move.

What forces are needed for greater change in movement?

The greater the object’s mass, the greater the force needed to move it, stop it or change its speed or direction.

### What are 4 examples of force and motion?

Climbing, jumping, running, chasing, throwing, and sliding all use force and motion.

### Does it take a stronger force to slow something down?

If an object must be slowed down quickly, the force applied to the object must be greater than what is needed for a gradual slowing down. For example, the greater the force applied to the brakes of a bicycle, the more quickly it will slow down or stop.

Why does it take more force to get an object moving?

The heavier the object and the faster it is moving, the greater its momentum and the harder it is to stop. If a truck and a car are travelling at the same speed, it takes more force to stop the truck because its greater mass gives it more momentum.

Does it take a stronger force to slow something down or speed it up?

## Does it take more force to slow something down than to speed it up?

If a heavy (more massive) object is in motion, more force must be applied to get the object moving faster. In order to slow down or stop a heavier (more massive) object, the force on that object must be greater than for a less massive object.

## What is the force of push and pull?

A push force or pull force is a force upon an object arising from the object’s or body’s interaction with another object. A push or a pull force also has direction; which means that it is a vector quantity if the magnitude or direction changes, it directly affects either type of force.

Does it take a stronger force to slow something down then speed it up?

For example if a ball is hit harder, it will speed up faster. If an object must be slowed down quickly, the force applied to the object must be greater than what is needed for a gradual slowing down. For example, the greater the force applied to the brakes of a bicycle, the more quickly it will slow down or stop.
