Force and Motion

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, keeping planets in orbit around the Sun.

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting between surfaces in contact.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is the formula for calculating distance?

Back

Distance = Speed × Time.

Front

What happens to an object's speed if a weaker force acts on it in the opposite direction?

Back

The speed of the object will decrease.

Front

What is the role of friction when pushing an object up a ramp?

Back

Friction opposes the motion, making it harder to push the object up the ramp.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects towards the center of the Earth, giving them weight.

Front

What is an example of a force?

Back

An example of a force is a push or pull, such as pushing a box.
