newtons laws

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 

__________ is the sum of all forces acting on an object. It is capable of accelerating a mass. 

• velocity
• gravity
• net force
• distance

What is the net force?

• 20 N 
• 0 N 
• 400 N 
• 40 N 

Which type of force(s) will cause a change in an object's motion?

• gravity
• zero net force
• balanced forces
• unbalanced forces

If you increase the force on an object, its acceleration

• decreases
• stays the same
• also increases
• stops

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

friction is a force that acts 

• in the same direction as the motion
• opposite to the direction of the motion
• opposite to the applied forces
• the same direction as the applied force

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
