Honors Force and Speed

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 

Because of inertia, a resting object ________.

• will remain at rest

• will move at a constant speed

• will eventually move

• is unbalanced

Newton's second law of motion states that an unbalanced force is equal to mass times:

• acceleration

• force

• motion

• inertia

As more unbalanced force is applied to an object, its acceleration:

• stays the same

• decreases

• increases

Newton's third law of motion states that for every action there is:

• an opposite, but equal reaction.

• an opposite and equal reaction.

• a reaction.

an object with mass 30.0kg moving with acceleration 2.0m/s2 the force that is effect on the object is

• 60N

• 15N

• 20N

• 22N

How much force is needed to accelerate a 3kg skateboard at 5m/s^2.

• 8N

• 1.6N

• 0.6N

• 15N

How much force is needed to accelerate a 25kg bowling ball at 2m/s².

• 50N

• 5N

• 12.5N

• 100N

If a 2kg bird is pushed by the wind with a force of 2N, how fast does the bird accelerate?

• 1 m

• 2 m/s²

• 4m/s²

• 1 m/s²

What is the magnitude (size) and direction of the net force?

• 14 N Down
• 14 N Up
• 6 N Up
• 6 N Down
