Newton's 1st Law of Motion

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

• Friction

• Inertia

• Mass

• Gravity

Which has more Inertia? (so needs more force to move)

• Truck

• A cat

• Ant

• A skateboard

What two factors do you use to describe a force?

• speed and mass

• strength and direction

• motion and direction

• distance and time

What kind(s) of objects have inertia?

• all objects with mass

• only objects in motion

• only objects at rest

• only objects whose motion is being changed

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

• gravity

• balanced forces

• zero net force

• unbalanced forces

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

• constant motion in a straight line

• accelerating motion in a straight line

• constant motion in an unpredictable direction

What can a force do?

• all of the above

• stop a motion

• start a motion

• change the direction of the motion

What is the name for a push or a pull?

• a movement

• speed

• a force

• density

What is Newton's 1st 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 and Gravity

An object following a straight-line path at a constant speed

• has zero acceleration

• has a net force acting in the direction of motion

• has no forces acting on it

• none of these
