1) If a baseball bat exerts a force on the baseball, what is the reaction?

2) If someone shoots a basketball, what is the reaction?

# data[].attributes.body
Mass is the amount of matter in an object

# data[].attributes.body
Force is any influence that tends to accelerate on an object, a push or a pull.

The golfer swinging the club at the ball is the action, the reaction is the golf ball exerts a force on the club of an opposite force.

# data[].attributes.body
For every action, there is an equal or opposite

reaction.

1) If the Net Force of an object is 21 Newtons, and the Acceleration is 7 m/s/s, what is the Mass? (units are kilograms)

A. 218kg C. 142kg

B. 147kg D. 132kg

2) If the Net Force of an object is 10 Newtons, and the Mass is 2 kilograms, what is the Acceleration? (units are m/s/s)

A. 7 m/s/s C.5m/s/s

B. 3 m/s/s D. 1.32 m/s/s

# data[].attributes.body
Acceleration is the rate of change of velocity per unit of time. A = F / M

# data[].attributes.body
A Net Force is the sum of all forces acting on an object.

F = M • A

# data[].attributes.body
The guys are accelerating the car forward of a greater net force and mass.

# data[].attributes.body
Fri ction is the force resisting the relative motion of solid surfaces

# data[].attributes.body
1) It takes what type of force to move a "still" object?

A. Unbalanced

B. Balanced

2) Why do we see objects eventually slow down after they are in motion?

# data[].attributes.body
Inertia is the tendency of an object to resist a change in motion, meaning a still object is still and a moving odject is still moving.

# data[].attributes.body
The acceleration of an object is depended by the net force and the mass of the object.

# data[].attributes.body
The Basketball is at rest until an unbalanced force acts upon it.

# data[].attributes.body
An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.
