Force and Motion

Front

What is gravity and how does it affect objects?

Back

Gravity is a force that attracts two bodies towards each other. It is the main force that causes objects to fall towards the Earth when dropped.

Front

What are the major forces acting on an airplane during takeoff?

Back

The major forces are lift, which allows the airplane to rise, and thrust, which propels it forward.

Front

What material is best for preventing sliding on an incline?

Back

A rubber mat is effective in preventing sliding due to its high friction coefficient.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

How does the height of a ramp affect the distance traveled by an object?

Back

The higher the ramp, the greater the potential energy, which can convert to kinetic energy, allowing the object to travel further.

Front

What is the definition of force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What role does friction play in motion?

Back

Friction is a force that opposes motion between two surfaces in contact, affecting how easily an object can move.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

How does mass affect gravitational force?

Back

The gravitational force between two objects increases with greater mass; more massive objects exert a stronger gravitational pull.
