# Newton’s 2nd Law Of Motion Definition

Newton's 2nd Law of Motion states that heavier objects need a larger force to make them move. For example, a metal ball needs more force to move as far as a plastic ball.

## Newton’s Laws of Motion

### Fun Facts

• Pushing a car requires more force than pushing a shopping cart.
• A heavier child on a swing needs more force to reach same height as a lighter child.
• Newton's 2nd law of motion is typically represented by the equation Force = Mass x Acceleration.

### Why Do We Need To Know About Newton's 2nd Law Of Motion

Newton’s 2nd law of motion helps us understand how forces make things move and why this is important for many jobs. For example, engineers need to know how the weight and type of material affect how something moves and the force needed when they design things that move.

This law is used in normal life, like getting off a boat safely, and in special jobs, like designing cars to survive crashes or building spacecraft. It helps make things like cars and planes safer and shows how useful and widespread this knowledge is.

Newton’s first law of motion states that an object's motion remains the same unless a force acts upon it. What would be an example of this law in action?
If a ball is still, it will remain still until a force, such as a kick, makes it move.
Newton’s second law of motion states that larger things need more force to move them than lighter things. What would be an example of this law in action?
One example is pushing a car or pushing a shopping cart. You would need much more force to push a car the same distance as a shopping cart.
Why do people need to know about Newton’s Laws of Motion?
Newton’s laws of motion are helpful when making predictions of motion. This might be important if you were trying to step off a boat onto a dock. If you push off the boat, it will move away from the dock a little, which would be important to know if you don’t want to end up in the water.
