Mrs. Rivera's Category 2 Force Motion and Energy STAAR Review

• can accelerate faster than the other two vehicles

• is traveling in the opposite direction from the other two vehicles

• is traveling on a curve in the road

• needs a large amount of force to move

• The reaction force is the force that causes the ball to move toward the bat

• The reaction force is the force applied to the bat by the player holding the bat

• The reaction force is the force that pulls the ball toward the ground

• The reaction force is the force of the ball on the bat

• The force are balanced so motion occurs

• The force are balanced so no motion occurs

• The force are unbalanced so motion occurs

• moving at a constant speed

• accelerating

• moving toward the north

• stopped

(a)  

• The wall pushes on the skater when the skate pushes on the wall

• The weels slow down and the skater stops

• The skater exerts a foce on the wall, and the wheels exert a force on the floor and begin to turn

• The friction of the floor decreases when the wheels roll on the floor

• There are no forces acting on the rock

• The only force actin on the rock is directed toward the sidewalk

• The force acting on the rock are all balanced

• The sidewalk exerts an unbalanced force on the rock
