Motion and Force

What is force?

• The speed of an object

• A push or pull upon an object resulting from the object's interaction with another object.

• The color of an object

• A type of energy

Give an example of a force in everyday life.

• Rainbow

• Gravity

• Unicorn

• Love

What is motion?

• Stillness

• Sound

• Motion

• Color

Explain the difference between speed and velocity.

• Speed is only applicable to objects in motion, while velocity is only applicable to stationary objects.

• Speed is the measure of how fast an object is moving, while velocity is the measure of how fast and in what direction an object is moving.

• Speed is the measure of distance traveled, while velocity is the measure of time taken to travel that distance.

• Speed and velocity are the same thing and can be used interchangeably.

What is Newton's first law of motion?

• An object in motion will eventually come to a stop

• An object at rest will start moving on its own

• An object in motion will change direction without any force

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

How does friction affect motion?

• Friction increases the speed of an object

• Friction has no effect on the motion of an object

• Friction causes the object to change direction

• Friction opposes the motion of an object

What is the relationship between force and acceleration?

• Force has no effect on acceleration

• Acceleration causes force

• Force is directly proportional to acceleration

• Force is inversely proportional to acceleration

Explain the concept of balanced and unbalanced forces.

• Balanced forces are equal in size and direction, resulting in a change in an object's motion.

• Balanced forces are equal in size and opposite in direction, resulting in no change in an object's motion. Unbalanced forces are unequal in size and/or direction, resulting in a change in an object's motion.

• Balanced forces are unequal in size and direction, resulting in a change in an object's motion.

• Unbalanced forces are equal in size and direction, resulting in no change in an object's motion.

How does mass affect an object's motion?

• Mass has no effect on an object's motion

• Mass decreases an object's inertia

• Mass increases an object's speed

• Mass affects an object's motion by influencing its inertia and the force required to change its velocity.

What are some examples of forces that can change the motion of an object?

• electricity, magnetism, nuclear, and chemical

• gravity, friction, air resistance, and applied force

• inertia, velocity, acceleration, and momentum

• magnetism, heat, light, and sound
