Newton's 2nd Law Review

A 20 kg bike accelerates at 10 m/s2.  what was the force

• 25 Newtons
• 20 Newtons
• 200 Newtons
• 10 Newtons

Football A has a greater mass than football B.  Which football will have greater acceleration when both are thrown with the same force in the same direction?

• Football A
• Football B
• They will have the same acceleration
• Mass has no effect on acceleration

What Unit do we Measure Force in? 

• Newtons
• Joules
• Force
• Don't know

A ball is rolling on the floor and a force pushes it in the same direction, what will happen?

• The ball will go faster.
• The ball will slow down.
• The ball will stop. 
• The ball will fly in the air.

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

What is Newtons 2nd law of motion?

• Pancakes 
• Force= Mass multiplied by acceleration
• For every action there is a equal and opposite  re-action.
• Law of gravity 

A 50 kg bicycle accelerates at 2 m/s2. what was the force

• 150

• 125

• 100

• 200

Accelerations are produced by

• forces.
•  velocities.
•  accelerations.
•  masses.

F=MA
An object of mass 10 kg is accelerated upward at 2 m/s².  What force is required? 

• 20 N
• 2 N
• 5 N
• 0 N

20 N is the

• mass
• weight
• force
• acceleration
