From the formula F= m.a., the letter m means ..........................

From the formula F= m.a., the letter f means ..........................

The second law of motion states that the force acting on an object is ................. to the mass of the object times its acceleration.

The second law of motion states that the force acting on an object is equal to the ................. of the object times its acceleration.

The second law of motion states that the force acting on an object is equal to the .mass of the object times its .............................

Objects of greater mass require greater force in order to ..........................

Objects of mass require ................... force in order to . accelerate.

If you apply a force to two different objects with ...............................masses, the force applied to the object with the smaller mass will be more noticeable than the same force applied to the larger object.

If you apply the same ..................... to a baseball and o a dump truck, you will be able to see the force acting on the baseball: the ball flies through the air

The word acceleration describes a change in .....................................

Acceleration is a ......................

Acceleration is a vector, which means it has two qualities’, speed and ............................

When acceleration and velocity point in the ....................... direction, an object accelerates (speeds up).

When acceleration and velocity point in ......................directions, an object decelerates (slows down)

When a constant net force acts on an object, the object ......................................... (change its velocity) at a constant rate.

The best example of of constant net force s is ..........................

If gravity is applied to an object at rest, the object accelerates in the ....................................of the force.

If the object is already in ..................... when it is acting upon by a constant net force, it may look like the object is speeding up, slowing down, or changing direction.
