Forces and Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in miles per hour (mph) or meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly it is speeding up or slowing down.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

How does friction affect motion?

Back

Friction slows down or stops the motion of an object by opposing its movement.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the greater the mass of an object, the more force is needed to accelerate it.

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.
