Newton's laws of motion

What is Newton’s first law of motion?

This states that an object at rest remain at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced external force

What is Newton's second law of motion?

This states that the acceleration of an object depends on the mass of the object and the amount of Force applied

What the formula for acceleration?

Acceleration = Net force/ Mass

What is Newton's third law of motion?

This states that for every action there is an equal and opposite reaction

What happens if net force acting on an object = 0?

The object’s motion will not change

When the forces acting on an object is unbalanced, what happens to its velocity?

Its velocity changes

Constant Mass + More Net force = what?

More acceleration

Different Mass + Same Net force = whar?

Less acceleration

Small Mass + Strong Net force = what?

More acceleration

Big mass + Stonger Net force = what?

More acceleration

Big mass + small net force = what?

Less acceleration

What are the factors that determine an object acceleration?

Mass of object & the amount of force applied

What is a spring balance used to measure?

Forces

What is a motion sensor used to measure?

Velocity

When doing an experiment you have to make sure what?

Only 1 variable is changing
