Newton´s Law
In which direction will an object move if acted on by multiple forces?
Forcenet = mass x acceleration
A tractor has a mass of 3000 kg and has an acceleration of 30 m/s. What is the amount of force the car will give if it hits a barn?
Unbalanced forces cause acceleration
How can two objects of different sizes exert the same amount of force on each other?
Acceleration depends on both force and mass. It helps the idea that unbalanced forces cause acceleration.
As force increases acceleration increases and when mass increases acceleration decreases.
When you hit a volleyball you feel the force on your hand
Why do objects at a constant velocity remain at that velocity?
Inertia- tendency of an object to resist a change in motion
They remain at a constant velocity because of friction. Say you are driving a car the wheel and the road are causing friction.
Acceleration depends on both force and mass. It supports the idea that unbalanced forces cause acceleration.
