KINETICS OF PARTICLES (NEWTON'S SECOND LAW)

What does Newton's Second Law of Motion state ?

• An object in motion stays in motion unless acted upon by an external forces

• For every action, there is an equal and opposite reaction.

• Objects at rest will always stay at rest

• The acceleration of an object depends on its mass and the applied force

Newton's Second Law shows the relationship between __________ , mass and acceleration.

• Force

• Distance

• Speed

• Energy

If you push a shopping cart, it accelerates. What factor increases the cart's acceleration ?

• Reducing the applied force

• Increasing the mass of the cart

• Applying more forces

• Keeping the cart stationary

What is the formula for Newton's Second Law of Motion?

•  F = ma
