Understanding Force and Motion

What is force in simple terms?

• A measure of mass

• A push or pull on an object

• A type of energy

• A state of motion

Which of the following best describes the characteristics of force?

• Size and speed

• Direction and velocity

• Size and direction

• Mass and acceleration

What happens when forces on an object are balanced?

• The object accelerates

• The object stops moving

• There is no change in motion

• The object moves faster

Which of the following is an example of balanced forces?

• A moving car stopping abruptly

• A book resting on a table

• A ball rolling downhill

• A pendulum swinging

Which of the following is a type of non-contact force?

• Friction

• Gravity

• Applied force

• Tension

What is friction?

• A force that pulls objects downward

• A force that opposes motion between two surfaces

• A force that keeps objects in orbit

• A type of tension

What type of force keeps a swing suspended?

• Friction

• Tension

• Magnetic force

• Electrostatic force

Which of the following forces is responsible for objects falling to the ground?

• Friction

• Tension

• Gravitational force

• Applied force

Air resistance is an example of:

• Gravitational force

• Friction

• Magnetic force

• Electrostatic force

Contact forces act:

• Without physical interaction between objects

• Between two objects physically touching each other

• Only on magnetic materials

• Only when objects are stationary
