Newtons first and second law

If you increase the force on an object, its acceleration

• decreases
• stays the same
• also increases
• stops

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

Which has more Inertia? 

• Truck
• Ant
• A cat
• A skateboard

F=MA
If you are pushing a 1000 kg car at 0.5 m/s², how many newtons would that be? 

• 2000 N
• 60N
• 500 N
• 12 N

What Unit do we Measure Force in? 

• Newtons
• Joules
• Force
• Don't know

F=MA 
Going down a hill a 12 kg sled has a force of 36 N. What is it's acceleration? 

• 2 m/s2
• 3 m/s2
• 432 m/s2
• 0.33 m/s2

F=Ma
An object of mass 300 kg is observed to accelerate at the rate of 4 m/s².  Calculate the force required to produce this acceleration. 

• 75 N
• .013 N
• 1200 N
• 2 N

F=Ma
A force of 200 N is exerted on an object of mass 40 kg that is located on a sheet of perfectly smooth ice.Calculate the acceleration of the object. 

• 5 m/s²
• 8000 m/s²
• 0.2 m/s²
• 1.32 m/s²
