### What is the relationship between force speed & acceleration?

## What is the relationship between force speed & acceleration?

Newton’s second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor. In short, force equals mass times acceleration.

## How is force velocity and acceleration related to each other?

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.

**Does force cause acceleration?**

An unbalanced force acting on an object causes it to accelerate. The bigger the unbalanced force acting on the object the bigger the acceleration of the object. The more mass the object has, the more inclined it is to resist any change to its motion.

**Why does force affect acceleration?**

A net force on an object changes its motion – the greater the net force, the greater the acceleration. More massive objects require bigger net forces to accelerate the same amount as less massive objects.

### What happens to acceleration if force is doubled?

As we increase the force on an object the acceleration increases proportionally. Therefore, if you double the force you double the acceleration. If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

### Does higher velocity mean higher force?

The faster you drive, the greater the impact or striking power of your vehicle. The laws of physics determine that the force of impact increases with the square of the increase in speed. So, if you double the speed of a car, you increase its force of impact four times.

**How are force and acceleration related to each other?**

“F” stands for force, “m” stands for mass and “a” stands for acceleration. Force is a push or pull that an object can exert on other objects. Acceleration is the rate of change of an object’s speed.

**When does speed stay the same when the forces become balanced?**

Eventually, the forces become balanced (the forward forces are the same size as the opposing forces). Once the forces become balanced, your speed stays the same. (It is like when a skydiver jumps out of a plane – speed will keep increasing until forces become balanced.) Push harder on the pedals to increase the force pushing you forwards.

#### What are the two main forces that affect speed?

Speed changes until forces become balanced. The two main forces that oppose your motion are aerodynamic drag ( air resistance) and rolling resistance of the tyres against the road caused as the tyre is compressed. When the forward forces are bigger than the opposing forces, you speed up (accelerate).
