Topic 2: Force and Motion Vocabulary

Displacement

• Displacement is the force acting on an object.
• Displacement is the change in position of an object in a straight line from its starting point to its ending point.

• Displacement refers to the speed of an object.
• Displacement is the total distance traveled by an object.

Distance

• Distance is the force acting on an object.

• Distance is the change in position of an object in a straight line from its starting point to its ending point.

• Distance refers to the speed of an object.

• Distance is the total length traveled by an object.

Reference (point)

• a place or object used for comparison to determine if something is in motion

• a source of information

• a letter recommending you for something

• to cite something from a book or story

Speed

• Speed is the time taken to travel a distance.
• Speed is the weight of an object in motion.
• Speed is the temperature of an object in motion.
• Speed is the rate at which an object covers distance.

Velocity

• Velocity is the speed of an object without direction.
• Velocity is the distance travelled over the time it took with a direction.

• Velocity is the total distance traveled over time.
• Velocity is the force applied to an object.

Uniform Motion

• Uniform motion involves changing speed in a circular path.
• Uniform motion is when an object accelerates in a straight line.
• Uniform motion refers to motion that varies in speed and direction.
• Uniform motion is motion at a constant speed in a straight line.

Slope

• Slope is calculated as rise over run.
• Slope has no relation to rise or run.
• Slope is calculated as width over height.
• Slope is the same as distance.

Balanced forces

• Balanced forces are unequal in size and direction and cause no change in motion.

• Balanced forces always result in motion and cause a change in motion.

• Balanced forces are equal in size and opposite in direction and cause no change in motion

• Balanced forces can only occur in one direction and cause a change in motion.

Force

• Acceleration

• a change in mass

• a push or pull

• effort + work

Inertia

• Inertia is the resistance of any physical object to any change in its velocity.
• Inertia is the force that causes an object to move faster.
• Inertia is the speed at which an object travels in a straight line.
• Inertia is the energy stored in a moving object.
