Horizontal forces act on two boxes, initially at rest, as shown. The magnitude (strength) and direction of the horizontal forces are also shown.
What happens to Box X and Box Y as a result of the forces?
A battery-powered toy submarine is moving through water at a
constant speed and at a constant depth below the surface. The diagram shows the submarine with arrows representing the directions but not the magnitudes of four forces acting on it.
The diagram shows a toy car on a track that is lying on the floor.
Select the choice to identify the net force acting on the car while the car is At Rest.
The diagram shows a toy car on a track that is lying on the floor.
Select the choice to identify the net force acting on the car while the car Begin to move Forward.
A basket of apples is pulled along a table. A friction force acts in a direction opposite to the motion of the basket.
Choose EACH of the 2 actions below that will Increase the force of friction between the basket and the table.
The motion graphs to the left show the motion of four objects over the same period of time. The lines on the graphs show objects that are speeding up, slowing down, and traveling at a constant speed.
After looking at the four graphs, choose the 2 graphs that are representing objects that are experiencing a net force of 0 Newtons.
Drag the terms on the left to match the definition on the right.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Rolling Friction | arrow_right_alt | The type of friction that exists between a parachute and the air. |
Static Friction | arrow_right_alt | The type of friction that occurs when a bicycle is ridden along a sidewalk. |
Sliding Friction | arrow_right_alt | The type of friction that occurs between objects that are not moving. |
Opposite | arrow_right_alt | The type of friction that occurs when you rub sandpaper against a piece of wood to smooth it. |
Fluid Friction | arrow_right_alt | A force that acts between surfaces that are touching. |
Friction | arrow_right_alt | The direction that friction ALWAYS acts relative to the direction of motion. |
An object moves at a constant speed.
What will happen to this object’s motion over time if no new forces are applied?
A block is sent sliding along a ramp. The green arrow represents the motion and direction of the block. Sliding friction is taking place between the block and the ramp.
What direction would the sliding friction be acting on the block as it slides along the ramp?
Choose the description from below that best describes the forces at work and the motion that would result in the diagram pictured to the left.
When four forces are applied to a box, the box begins to move. the diagram’s arrows show the direction and the magnitude of the four forces acting on the box.
In which direction will the box move?
All aspects of an object's motion are brought about by balanced forces and / or by unbalanced forces. Choose each (4) of the statements below that are true about an unbalanced force acting on an object.
All aspects of an object's motion are brought about by balanced forces and / or by unbalanced forces. Choose EACH (3) of the statements below that are true about a balanced force acting on an object.
How far did the vehicle travel during the first two seconds?
In the space below, type in the net force acting on the box in diagram C.
( TYPE JUST THE NUMBER)
What happens when two forces act in the same direction?
The tendency of an object to resist a change in its motion is......? (remember julius sumner miller)
Balanced or Unbalanced
