Force and Motion

What is happening in this picture?

• There is it continues in its existing state of rest or uniform motion in a straight line,unless that state is changed by an external force called INERTIA

• The rate of change of position of an object in any direction called SPEED

• There is gravitational pull and magnetic push happening called FORCE.

• I don't have an answer to this.

What kind of force is this?

• Drag forces appear whenever there is motion in air or water or in any other fluid

• Gravitational force, pulls objects with mass toward each other.

• Friction is a force that opposes relative motion between surfaces in contact.

• The kid is just playing.

What is in the picture?

• The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges.

• Electric force is the attractive force between the electrons and the nucleus

• When a metal spring is stretched or compressed, it is displaced from its equilibrium position. As a result, it experiences a restoring force that tends to retract the spring back to its original position. This force is called the spring force.

• I can't figure it out.

What type of force is this?

• Normal force is the force that surfaces exert to prevent solid objects from passing through each other.

• Gravitational force, pulls objects with mass toward each other. We often think about the force of gravity from Earth. This force is what keeps your body on the ground. But any object with mass exerts a gravitational force on all other objects with mass.

• Electrostatic forces are non-contact forces; they pull or push on objects without touching them.

• The average distance to the moon is 382,500 kilometers. The distance varies because the moon travels around Earth in an elliptical orbit.

What is the speed of a bobsled whose distance- time graph indicates that it traveled 100 m in 25 seconds?

• 4m/s

• 67m/s

• 0m/s

• No more time to answer.

When applying a force to push an object through a distance, you transfer _____ to the object.

• Speed

• Motion

• Energy

Which of the following is an example of exerting a force?

• a train speeding down a track

• a carpenter hammering a nail

• a child running through a field

• an airplane soaring through the sky

If a bicyclist travels 30 kilometers in two hours, her average speed is _______________.

• 60Km/h

• 2Km/h

• 15Km/h

• Sleeping time
