Force and Motion

What is friction?

• An opposing force that makes objects in motion slow down.

• A force that accelerates objects in motion.

• A type of energy that objects possess.

• A force that allows objects to move freely without resistance.

What causes an object to move?

• Balanced forces

• Frictional forces

• Unbalanced forces

• Gravitational forces

What is the difference between speed and velocity?

• Speed is the distance traveled per unit of time, while velocity includes direction.

• Speed is a vector quantity, while velocity is a scalar quantity.

• Speed can change direction, while velocity cannot.

• Speed is always greater than velocity.

What is the role of gravity in motion?

• It pulls objects towards the center of the Earth, affecting their motion.

• It pushes objects away from the Earth, increasing their speed.

• It has no effect on the motion of objects in space.

• It only affects objects that are in free fall.

What does gravity do?

• It is the force that repels objects away from each other.

• It is the force that attracts objects towards each other.

• It is the force that keeps objects stationary in space.

• It is the force that causes objects to float.

What can force do to an object?

• Make it disappear

• Change its color

• Accelerate, slow down, keep it in place, or change its shape.

• Make it heavier

What is the formula for calculating force?

• Force = mass + acceleration (F = m + a)

• Force = mass × acceleration (F = ma)

• Force = mass / acceleration (F = m / a)

• Force = mass - acceleration (F = m - a)

What is the relationship between force and motion?

• Force is required to change the motion of an object.

• Force is not related to motion at all.

• Motion can occur without any force acting on an object.

• Force only affects the speed of an object, not its direction.

What is inertia?

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to move in a circular path.

• The mass of an object multiplied by its velocity.

• The energy stored in an object due to its position.

What is the effect of unbalanced forces on an object?

• They cause the object to remain at rest.

• They cause the object to accelerate in the direction of the net force.

• They cause the object to move at a constant speed.

• They have no effect on the object's motion.
