What is energy?
Energy is a type of matter.
Energy is the speed of light.
Energy is a form of currency.
Energy is the capacity to do work.
Name two types of energy.
Kinetic energy, Potential energy
Chemical energy
Nuclear energy
Thermal energy
What happens to energy when it changes form?
Energy can be created during the transformation.
Energy becomes unmeasurable after changing form.
Energy is conserved but changes its form.
Energy is lost when it changes form.
What is kinetic energy?
Kinetic energy is the energy stored in an object at rest.
Kinetic energy is the energy associated with an object's temperature.
Kinetic energy is the energy of an object in motion.
Kinetic energy is the energy released during a chemical reaction.
What is potential energy?
Kinetic energy is the energy of motion.
Potential energy is the energy of heat.
Potential energy is the energy released during a chemical reaction.
Potential energy is the energy stored in an object due to its position or state.
How does energy affect motion?
Energy can only increase the temperature of an object.
Energy influences motion by enabling objects to move or change their speed and direction.
Energy has no effect on motion.
Energy only affects stationary objects.
What is a force?
A force is a type of energy that cannot be measured.
A force is a fixed quantity that does not change.
A force is an object that moves on its own.
A force is an interaction that causes an object to change its motion.
What are the two types of forces?
Contact forces and non-contact forces
Static forces and dynamic forces
Frictional forces and gravitational forces
Balanced forces and unbalanced forces
What is the relationship between force and motion?
Force has no effect on motion.
Motion is independent of force.
Force only affects stationary objects.
Force causes changes in motion, as described by Newton's laws of motion.
What is friction?
Friction is the force that opposes the relative motion of two surfaces in contact.
Friction is the energy lost when two surfaces are heated together.
Friction is the force that enhances the relative motion of two surfaces in contact.
Friction is the attraction between two surfaces that keeps them together.
How does friction affect movement?
Friction opposes movement, slowing down or stopping objects.
Friction has no effect on movement whatsoever.
Friction enhances movement, making objects go faster.
Friction only affects stationary objects, not moving ones.
What is gravity?
Gravity is a type of energy that powers machines.
Gravity is the speed at which objects fall.
Gravity is the temperature of an object in space.
Gravity is the force that attracts two bodies with mass towards each other.
How does gravity affect objects on Earth?
Gravity only affects objects in space, not on Earth.
Gravity has no effect on objects, allowing them to float freely.
Gravity pulls objects toward the Earth, giving them weight and causing them to fall.
Gravity pushes objects away from the Earth, making them lighter.
What is Newton's first law of motion?
An object will remain in motion only if it is in a vacuum.
An object will remain at rest or in uniform motion unless acted upon by an external force.
An object will change direction only when a force is applied.
An object will accelerate unless a force is applied.
What is an example of an action-reaction pair?
A person pushing a wall causes the wall to push back with no movement.
A balloon deflating causes the air to rush into the balloon.
A car accelerating causes the road to move beneath it.
A person jumping off a boat causes the boat to move in the opposite direction.
