Newton's Laws

Select Newton's First Law

• Force = mass x acceleration

• Objects will not change their motion unless acted on by an external force.

• When two objects interact, they exert equal but opposite forces on each other.

Select Newton's Second Law

• Force = mass x acceleration

• Objects will not change their motion unless acted on by an external force.

• When two objects interact, they exert equal but opposite forces on each other.

Select Newton's Third Law

• Force = mass x acceleration

• Objects will not change their motion unless acted on by an external force.

• When two objects interact, they exert equal but opposite forces on each other.

If two forces acting on an object are equal, the object could be...

• accelerating

• decelerating

• travelling at a steady speed

• stationary

Which diagram represents a car travelling at a steady speed?

• 
• 
• 

Which diagrams represent a car accelerating?

• 
• 
• 

The larger the resultant force on an object, the __________ the acceleration.

The larger the mass of an object, the __________ the acceleration.

Select the correct equations.

• Force = mass / acceleration

• acceleration = Force / mass

• Force = mass x acceleration

• mass = Force / acceleration

• acceleration = Force x mass

A car with a mass of 2500 kg accelerates at a rate of 0.5 m/s². Calculate the force acting on the object.
